A low profile modular switch, the switch including a switch plate including an actuator and a housing, and a sense plate including a switch mechanism configured to interface with the actuator, and a flat wiring harness having one end joined to the sense plate and another end having a connector, wherein tactile feel of the modular switch is determined by a property of the switch plate independent of the sense plate.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a system and a method for a low profile switch with a flat wire harness.
2. Background Art
Referring to
FIG. 1
a
, a diagram
10
illustrating a conventional switch bank (or array) is shown. The switch bank
10
is a stacked (i.e., overlaid) structure. The switch back
10
is implemented to carry a low voltage DC signal. The switch bank
10
is a group of normally open, single pole, single throw (NO, SP, ST) momentary contact device non-tactile switches. The switch bank
10
includes a graphic overlay
12
having painted or printed on symbols
14
a
-
14
n
that relate to numbers, arithmetic operators, and the like depending on the switch bank
10
application. In one example, the overlay
12
is disposed over an electrostatic discharge (ESD)/electromagnetic interference (EMI) shield
16
. In another example, the overlay
12
is disposed directly over a top membrane
18
. The membrane
18
has a number of contacts
20
a
-
20
n
that align with the respective symbols
14
a
-
14
n
when the switch bank
10
is properly assembled.
The switch bank
10
further includes a spacer
22
disposed under the membrane
18
. The spacer
22
has holes
24
a
-
24
n
that generally align with respective contacts
20
a
-
20
n
in membrane
18
. A bottom membrane (or circuit board)
30
includes circuit grids
32
a
-
32
n
that generally align with respective contacts
20
a
-
20
n
such that a respective circuit is closed when a user sufficiently depresses the respective symbol
14
. The switch bank
10
can also include a subpanel (i.e., substrate, back cover, etc.)
34
that generally provides physical support. The stackup or overlay of the respective symbol
14
, contact
20
, hole
24
, and grid
32
forms an individual switch in the switch bank
10
.
The conventional switch bank
10
has a number of deficiencies that include when the switch bank
10
is manufactured the layers (i.e., the overlay
12
, the membrane
18
, the spacer
22
, the circuit board
30
, and the subpanel
34
) can be difficult to align such that the respective symbols, holes, and circuits align properly, the switch bank
10
is not lighted or backlit, the overlay
12
and the symbols
14
are not registered (i.e., the surface of the overlay
12
is substantially smooth such that a user can not readily discern switch location and type by feel), and the switch bank
10
does not provide tactile feedback feel to the user.
However, the user generally prefers switches that have a tactile feel such that actuation of the switch provides positive feedback such as a snap to indicate switch operation. A tactile switch can be defined (e.g., by American Society for Testing and Materials standards ASTM F 1570-01e1 and F 1997-99) as a switch having a tactile ratio greater than zero. Furthermore, tactile indication of the respective switch symbol and/or switch lighting is desirable in many applications such that the user can readily identify the appropriate switch in a low light environment.
Referring to
FIG. 1
b
, a diagram illustrating a conventional switch bank
10
′ is shown. The conventional switch bank
10
′ is similar to the switch bank
10
. To provide a tactile feel, the switch bank
10
′ includes a spacer
40
disposed between the overlay
12
and a membrane
18
′. The membrane
18
′ implements domes
20
a
′-
20
n
′ instead of the membrane contacts
20
a
-
20
n
of switch bank
10
. Depressing the membrane
12
at a symbol
14
of the switch bank
10
′ collapses a respective dome
20
′ to provide the tactile response to the user. However, the conventional switch bank
10
′ has a number of deficiencies. During manufacturing the layers can be difficult to align such that the respective symbols, domes, holes, and circuits align properly. The switch bank
10
′ is not lighted, and the overlay
12
and the symbols
14
do not provide tactile registration.
Referring to
FIG. 1
c
, a diagram illustrating a conventional switch bank
10
″ is shown. The switch bank
10
″ is implemented similarly to the switch banks
10
and
10
′. To provide a tactile feel switch bank, the switch bank
10
″ has a non-tactile overlay
12
″ made of an elastomer rubber having raised symbols
14
″ (i.e., buttons) to provide the tactile registration. The membrane
18
′ can provide a limited tactile feel. The switch bank
10
″ also substitutes an adhesive spacer
22
″ for the spacer
22
. However, during manufacturing the layers can be difficult to align such that the respective symbols, domes, holes, and circuits align properly. The switch bank
10
″ is not lighted, and the tactile feel provided by the membrane
18
′ is reduced by the relatively thick and soft buttons
14
″.
Referring to
FIG. 2
a
, a diagram illustrating an exploded, sectional view of a conventional switch (or cell)
50
is shown. A number of the switches
50
may be integrated (i.e., combined or implemented as an array) to provide a switch bank similar to the switch banks
10
,
10
′, and
10
″. The switch
50
includes an overlay/bezel
52
with a hole that has a shape similar to a key top (or cap)
54
. The key top
54
is hard plastic and protrudes through the bezel
52
and the bezel
52
generally positions the key top
54
. The key top
54
is disposed onto a rubber keypad
56
that has a carbon or metallic pill (or puck)
58
on top of a dome
60
. The dome
60
is disposed above a bottom membrane (or circuit board)
62
that has a circuit grid
64
. The switch
50
may be disposed on a subpanel (i.e., substrate, back cover, etc.)
66
that provides physical support. To actuate the switch
50
, the user depresses the key top
54
, the key top
54
collapses the dome
60
, and the pill
58
contacts the grid
64
to complete a circuit. The dome
60
provides tactile feel to the switch
50
, however, the tactile feel is limited by the interface between the cap
54
and the pill
58
.
The conventional switch bank
50
is not sealed at the interface between the bezel
52
and the key top
54
and debris can enter the interface and interfere with proper switch operation. During manufacturing the layers (i.e., the bezel
52
, the key top
54
, the keypad
56
, and the membrane
62
) can be difficult to align (i.e., gaps can be difficult to control) such that the respective key tops, domes, and circuits align properly, and the switch
50
is not lighted. Each key top
54
is typically individually molded, painted and assembled into the switch
50
assembly.
The alignment of the bezel
52
and the key top
54
is critical to the proper operation and feel of the switch
50
. When the gaps between the bezel
52
and the key top
54
are not properly sized or aligned the key tops
54
can be too tight and bind, too loose and wobble and result in reduction or loss of tactile feel, and in any case fail to cause the pill
58
to properly contact the grid
64
.
Referring to
FIG. 2
b
, a diagram illustrating a conventional switch (or cell)
50
′ is shown. The switch
50
′ is implemented similarly to the switch
50
. The switch
50
′ includes a tactile rubber keypad
56
′ having a formed key
54
′ that protrudes through the bezel
52
. The pill
58
is fixed to the underside of the key
54
′. The conventional switch bank
50
′ has similar deficiencies to the switch
50
.
Referring to
FIG. 2
c
, a diagram illustrating a conventional switch (or cell)
50
″ is shown. The switch
50
″ is implemented similarly to the switches
50
and
50
′. The switch
50
″ includes a non-tactile rubber keypad
56
″ having a formed key
54
″ that protrudes through the bezel
52
. The pill
58
is fixed to the underside of the key
54
″. A metal dome
60
″ is disposed to align with the pill
58
and to provide tactile feel. A spacer
68
having a hole
70
is disposed such that when the switch
50
″ is actuated, the pill
58
travels through the hole
70
to contact the grid
64
. The conventional switch bank
50
″ has similar deficiencies to the switch
50
.
Referring to
FIG. 3
, a diagram illustrating a conventional switch (or cell)
50
′″ is shown. The switch
50
′″ is implemented similarly to the switch
50
. The switch
50
′″ includes a light emitting diode (LED) or other appropriate light source
80
disposed such that the switch
50
′″ is lighted (i.e., back-lit). The conventional switch
50
′″ has similar deficiencies to the switch
50
except that the switch
50
′″ provides lighting.
The conventional switch banks
10
,
10
′,
10
″,
50
,
50
′,
50
″, and
50
′″ have additional deficiencies in that the conventional switch banks are an integrated apparatus or assembly, thus the tactile feel for the switch bank can be difficult to “tune” or adjust to meet the design criteria of a particular application, when the conventional switch banks
10
,
10
′,
10
″,
50
,
50
′,
50
″, and
50
′″ are implemented as a modular package (e.g., having separate integral actuator and switching device assemblies) a “dead zone” can be perceived during switch actuation due to a gap between the actuator and the switching device, the conventional switch banks
10
,
10
′,
10
″,
50
,
50
′,
50
″, and
50
′″ include a relatively large number of components that can be expensive as well as difficult to align properly, the conventional switch banks
10
,
10
′,
10
″,
50
,
50
′,
50
″, and
50
′″ are relatively thick and can be difficult to package in space restrictive installations, and the conventional switch banks
10
,
10
′,
10
″,
50
,
50
′,
50
″, and
50
′″ are generally a rather cumbersome package to install in connection with some applications that have limited room and require efficient use of space such as vehicle switch implementations.
Thus, there exists a need for an improved system and an improved method for a low profile switch with a flat wire harness. The present invention may provide a modular low profile switch package wherein tactile feel can be adjusted to meet the design criteria of a particular application, backlighting may be easily implemented, and the switch may be assembled easily. The low profile switch of the present invention may provide easy installation, and may be implemented with relatively fewer components, with higher system quality and lower system cost when compared to conventional approaches.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
With reference to the Figures, the preferred embodiments of the present invention will now be described in detail. Generally, the present invention provides an improved system and an improved method for a modular low profile switch with a flat wire harness. The present invention may provide a modular low profile switch package wherein tactile feel can be adjusted to meet the design criteria of a particular application, backlighting may be easily implemented, and the switch may be assembled easily. The low profile switch of the present invention may provide easy installation, and may be implemented with relatively fewer components, with higher system quality and lower system cost when compared to conventional approaches. The modular switch of the present invention generally comprises a switch plate and a sense plate. Tactile feel of the low profile switch of the present invention may be determined by a property of the switch plate independent of the sense plate.
Referring to
FIG. 4
, a diagram illustrating a switch (or integrated switch bank)
100
according to the present invention is shown. The switch
100
is generally implemented as a low profile modular switch with a flat wire harness. The switch
100
generally comprises a switch plate (or package)
102
, a sense plate (or package)
104
, a connector
106
, and wire harness
108
. The switch plate
102
and the sense plate
104
generally are implemented as modular components to the switch
100
(i.e., the switch
100
may be implemented as a modular integrated switch bank). The switch plate
102
is generally configured to operate with (e.g., interface with, be fastened or joined to, etc.) the sense plate
104
.
In one example, alternative implementations of the switch plate
102
(described in more detail in connection with FIGS.
5
(
a-e
)) may be implemented in connection with the sense plate
104
. As such, surface touch and feel, actuation tactile parameters (e.g., feel, sensation, travel, feedback, etc.), visual appearance, audible feedback, ergonomics, human factors, and the like of the switch
100
may be “tuned” (i.e., adjusted, set, controlled, determined, selected, etc.) to meet the design criteria of a particular application. Since the switch
100
may be implemented having “tuning” in the switch plate
102
independent of the sense plate
104
, the switch
100
may reduce or eliminate perception of a “dead” zone during actuation that may be present in conventional approaches to modular switches and the switch
100
may have tactile parameters that are implemented to meet the design criteria of a particular application. In one example, the tactile parameters of the switch
100
may be determined through selection or adjustment of the respective properties of the components of the switch plate
102
independent of the sense plate
104
component properties. In another example, the tactile parameters of the switch
100
may be determined through selection or adjustment of the respective properties of the components of the switch plate
102
in connection with the sense plate
104
component properties.
In one example, the switch plate
102
generally comprises a housing
120
that has a slot
122
, and at least one actuator (i.e., button, knob, cap, etc.)
124
(e.g., actuators
124
a
-
124
n
). The sense plate
104
may be inserted (e.g., positioned, slid, placed, etc.) into the slot
122
to assemble the switch
100
. In another example (see, for example, FIGS.
6
(
a-c
)), the switch housing
120
may be implemented without the slot
122
and the sense plate
104
may be fastened (or joined) directly to the housing
120
(i.e., to the switch plate
102
).
The plate
104
is generally held in place in (or fastened to) the housing
120
using fastening (not shown) such as screws, rivets, clips, formed ridges, and the like. The switch
100
is generally configured such that the plate
104
may be removed from the housing
120
to provide access to the switch plate
102
and the sense plate
104
for servicing, cleaning, etc. In another example, the plate
104
may be fastened to the housing
120
using heat staking, adhesive, welding, riveting, etc. to form a substantially permanent joining of the switch plate
102
and the sense plate
104
.
The sense plate
104
generally comprises a membrane (i.e., panel, substrate, plate, etc.)
130
having at least one switching mechanism
132
(e.g., mechanisms
132
a
-
132
n
) that are configured to interface electrically and/or mechanically with respective actuators
124
a
-
124
n
when the sense plate
104
is assembled into (or aligned with, fastened to, etc.) the switch package
102
. When a user pushes, twists, clicks, actuates or otherwise operates an actuator
124
, an electrical circuit comprising a respective mechanism
132
and one or more wires in the wire harness
108
is generally completed or opened.
The mechanism
132
may be implemented as a grid, a dome structure, at least one finger spring, at least one wave spring, or any other appropriate apparatus to meet the design criteria of a particular application. In one example, the sense plate
104
may further comprise at least one light source
134
(e.g., light sources
134
a
-
134
n
). The light source
134
is generally implemented when the switch
100
is lighted (or backlit). The light source
134
is generally implemented as a light emitting diode (LED), light pipe, fiber optic, luminescent surface device, and the like.
The wire harness
108
generally connects to the sense plate
104
using a splice joint
136
at one end and interfaces to the connector
106
at another end. The joint
136
is generally disposed at an edge of the sense plate
104
. The connector
106
is generally connected (i.e., electrically interfaced) to devices (not shown) external to the switch
100
such as motors, control modules, other wire harnesses, etc. In one example, the switch
100
may be implemented without the connector
106
and the wire harness
108
may be directly connected to the devices external to the switch
100
. While the wire harness
108
is illustrated as a flat harness, the harness
108
may be implemented having any appropriate shape (e.g., substantially round, oval, rectangular, etc.) to meet the design criteria of a particular application.
Referring to FIGS.
5
(
a-e
), detailed sectional diagrams illustrating example embodiments of the switch (or cell)
100
in accordance with the present invention are shown. A number of the switches
100
may be integrated (i.e., combined, configured, implemented as an array, etc.) to provide an integrated switch bank. The switch
100
is generally implemented as an electrical switch. The switch package
100
is generally implemented as a modular switch package comprising at least one implementation of the switch plate (or package)
102
, and the sense plate
104
.
Referring in particular to
FIG. 5
a
, a sectional view illustrating an example of the switch
100
is shown. The actuator
124
generally comprises a cap (or knob)
150
affixed to and positioned above a gel pack
152
. The actuator
124
is generally held (i.e., mounted, positioned, disposed, etc.) in the housing
120
using a suspension
154
. When the user operates (i.e., pushes, actuates, etc.) the cap
124
, the gel pack
124
generally contacts the mechanism
132
. The suspension
154
may be implemented as molded rubber or elastomer (e.g., a thermoplastic elastomer, TPE), a flexible foam material such as a urethane foam, and the like. The suspension
154
is generally implemented as a low compliance suspension. The suspension
154
may provide sealing between the housing
120
and the actuator
124
. In one example, the cap
150
may be implemented using a molded hard plastic. In another example, the cap
150
may be implemented using a molded soft plastic, rubber, TPE and the like.
The gel pack
152
may be implemented having an appropriate thickness, and filled with a gel having an appropriate compliance to meet the touch and feel design criteria or parameters of a particular application. In one example, the tactile parameters of the switch
100
as illustrated in
FIG. 5
a
may be adjusted by appropriate implementation of properties (e.g., material, thickness, etc.) of the cap
150
, the gel pack
152
, and the suspension
154
such as compliance, stiffness, flexibility, etc. in connection with the mechanism
132
. In another example, the tactile parameters of the switch
100
may be adjusted by appropriate implementation of properties of the cap
150
, the gel pack
152
, and the suspension
154
such as compliance, stiffness, flexibility, etc. independent of the mechanism
132
.
Referring in particular to
FIG. 5
b
, a sectional view illustrating another example of the switch
100
is shown. The actuator
124
generally comprises a sealed sac (e.g., vessel, bag, pouch, etc.) that may be filled with a filler
160
, and a subplate
162
. In one example, the filler
160
may be implemented as a liquid. In another example, the filler
160
may be implemented as a gel. In another example, the filler
160
may be implemented as a gas. However, the filler
160
may be implemented as any appropriate material to meet the design criteria of a particular application. The subplate
162
may provide a rigid (i.e., stiff, noncompliant, etc.) surface that contacts and actuates the mechanism
132
when a user operates the switch
100
. The tactile parameters of the switch
100
as illustrated in
FIG. 5
b
may be adjusted by appropriate implementation of properties of the sac
124
, the suspension
154
, and the filler
160
such as compliance, stiffness, flexibility, etc. in connection with the mechanism
132
. In another example, the tactile parameters of the switch
100
may be determined independent of the mechanism
132
.
Referring in particular to
FIG. 5
c
, a sectional view illustrating another example of the switch
100
is shown. The actuator
124
generally comprises a vented sac (e.g., vessel, bag, pouch, etc.). The filler
160
may be implemented as air. The sac (i.e., actuator)
124
further comprises at least one vent
170
(e.g., vents
170
a
-
170
n
). When the switch
100
is operated, the air
160
is generally exhausted from the sac
124
through the at least one vent
170
. When the switch
100
is released, the air
160
is generally inlet to the sac
124
through the at least one vent
170
. The tactile parameters of the switch
100
as illustrated in
FIG. 5
c
may be adjusted by appropriate implementation (e.g., number of, size of, etc.) of the at least one vent
170
, properties of the sac
124
and the suspension
154
such as compliance, stiffness, flexibility, etc. in connection with the mechanism
132
. In another example, the tactile parameters of the switch
100
may be determined independent of the mechanism
132
.
Referring in particular to
FIG. 5
d
, a sectional view illustrating another example of the switch
100
is shown. The actuator
124
generally comprises a sealed sac having a filler
160
. The sac
124
and the filler
160
may be implemented similar to the respective sac
124
and filler
160
of the switch
100
illustrated in
FIG. 5
b
. However, the switch
100
as illustrated in
FIG. 5
d
may be implemented without the suspension
154
and the subplate
162
. The sac
124
may be connected (e.g., mounted, fastened, adhered, welded, etc.) directly to the housing
120
. The sac
124
may directly contact the mechanism
132
when the switch
100
is operated. In one example, the tactile parameters of the switch
100
may be determined through selection or adjustment of properties of the sac
100
, the filler
160
such as compliance stiffness, flexibility, etc., and the mechanism
132
. In another example, the tactile parameters of the switch
100
may be determined independent of the mechanism
132
.
Referring in particular to
FIG. 5
e
, a sectional view illustrating another example of the switch
100
is shown. The switch
100
may be implemented similarly to the switch
100
illustrated in
FIG. 5
a
. The switch
100
may further comprise a button suspension
180
. The button suspension
180
is generally implemented to proved supplemental suspension for the actuator
124
in addition to the suspension
154
. However, in another example (not shown), the suspension
154
may be deleted and the button suspension
180
may provide the suspension for the actuator (i.e., button, cap, etc.)
124
. In any case, the properties of the suspension
180
such as compliance, stiffness, flexibility, etc. may be implemented or adjusted to provide tactile parameters for the switch
100
in connection with the suspension
154
(when implemented) and the mechanism
132
. In another example, the tactile parameters of the switch
100
may be determined independent of the mechanism
132
.

(
a-c
) the switch
100
may be advantageously implemented in connection with vehicle interior applications such as the door trim panel
202
, the instrument panel
210
, and the console
220
when compared to conventional switch approaches since the switch
100
is a low profile modular switch package with a flat wiring harness. The switch plate
102
and the sense plate
104
(and the connector
106
and the wire harness
108
) may be installed in separate operations and then joined to assemble the switch
100
. As such, installation of the switch
100
may more easily be performed when compared to more cumbersome and thick conventional switch approaches.
As is readily apparent from the foregoing description, then, the present invention generally provides an improved apparatus (e.g., the switch
100
) and/or an improved method for a modular low profile switch bank package. The present invention may provide a modular low profile switch package wherein tactile feel can be adjusted to meet the design criteria of a particular application, backlighting may be easily implemented, and the switch may be assembled easily. The low profile switch of the present invention may provide easy installation, and may be implemented with relatively fewer components, with higher system quality and lower system cost when compared to conventional approaches.
While embodiments of the invention have been illustrated and described, it is not intended that these embodiments illustrate and describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention.
