The present disclosure generally relates to the field of automobiles. Particularly, the present disclosure relates to an integrated three position rocker switch for vehicles. Further, embodiments of the present disclosure disclose the construction and mechanism of an integrated three position rocker switch.
The information in this section merely provides background information related to the present disclosure and may not constitute prior arts:
Generally, vehicles such as, but not limited to, two-wheelers, are equipped with switches such as turn indicator switches, head lamp switches, engine kill switches etc, for operating the various electronic functions of the vehicle. One such switch is a dimmer switch (100) configured to regulate the headlamp of the vehicle. Conventionally, the functions of high beam and low beam is achieved by means of a singular switching device having a knob and in case of an EKS switch, the functions of ON and OFF is achieved by means of a singular switching device having a Knob. For achieving the pass function, the rider has to separately activate the ‘pass’ switch provided on the handlebar of the vehicle. Another example of one such switch is the EKS switch configure to ON/OFF an engine of a vehicle. The functions of ON and OFF is achieved by means of a singular switching device having a Knob. For achieving the Self-Start function, the rider has to separately activate the ‘Self-Start’ switch provided on the handlebar of the vehicle.

Accordingly, the integrated three position rocker switch described with reference to the figures and specific embodiments; this description is not meant to be constructed in a limiting sense. Various alternative embodiments from part of the present disclosure.
Now, referring to
The knob assembly (4) comprises a knob (406) being pivotally supported in the housing (1), wherein the knob (406) is configured to operate the first and second micro-switches (2, 3). The knob assembly (4) has a first protrusion (401), a second protrusion (402), a pocket (403) and pivoting hole (404) as shown in
The first micro-switch (2) is coupled with the knob assembly (4) in the housing (1), wherein the first micro-switch (2) is disposed in the housing (1). The second micro-switch (3) is disposed in the housing in vicinity of the first micro-switch (2). In an embodiment, the second micro-switch (3) is mounted on the housing (1) on opposite end from the mounting of the first micro-switch (2). The knob (406) is configured to move in multiple positions for actuating the first and second micro-switches (2, 3) to perform more than one operation. In an embodiment, the knob is adapted to move in three positions as shown in
As shown in

When the user actuates the knob (406) from a first position to a third position, the plunger (6) moves in longitudinal direction to actuate the second micro-switch (3) and, alternatively, the lever (9) presses the first micro-switch (2) to actuate the first micro-switch (2). Upon release of the actuating force from knob (406), the spring (5) tends to expand or de-energize which causes movement of the plunger (6). The first and second protrusions (401, 402) are configured to be engaged with the first and second micro-switches (2, 3) with the movement of the knob for actuating the first and second micro-switches (2, 3). In an embodiment, the actuation of the first micro-switch (2) and the second micro-switch (3) takes place in alternative manner. In first position as shown in
In present disclosure, the dimmer switch (100) with pass module has two separate micro-switches, each with separate switching outputs, for ensuring that the switch is working or not-working as per Functional Safety Requirement (FSR). The switching outputs include NO/NC, open or closed circuit. In accordance with the connection of the first and second micro-switches (2, 3), the first and second micro-switches (2, 3) communicate with the control unit and the, the control unit identify the working or non-working condition of the dimmer switch (100. The dimmer switch (100) has compact size as the number of parts are reduced. The switch transmits two redundant signals for single switch operation. These two signals are transmitted while the switch is activated/deactivated. The strategy used to ensure reliability of the switch is to use two signals wherein one signal is analog signal and other is CAN signal, to manage the critical nature of the switch state. The usage of redundant switch inputs increases the confidence level in determining an intentional and identifying an unintended switch transition. Both the redundant outputs are transmitted to electronic control unit for managing critical functionality of vehicle and ensure unintended activation of vehicle which may cause continuous run resulting in overheat, vehicle in run position without resulting in accident.
