Continuing to refer to FIGS. 36-42, in this exemplary embodiment the device module 70 includes one or more sensors 50, an electrical wiring device 72, a mounting plate 74 and a seal member 88. In the embodiment shown, the electrical wiring device 72, mounting plate 74 and the seal member 88 are separate components where electrical wiring device 72 and mounting plate 74 are joined together with, for example, mechanical fasteners, and the sealing member 88 is positioned, e.g., sandwiched, between a cover 96 of the electrical wiring device 72 and the mounting plate 74. On other embodiments, the electrical wiring device 72, mounting plate 74 and the seal member 88 may be integrally or monolithically formed as a single unit, or the electrical wiring device 72, mounting plate 74 and the seal member 88 may be separate components joined together with, for example, adhesives or mechanical fasteners. In this exemplary embodiment, the one or more sensors 50 are included or embedded in the electrical wiring device 72.
Continuing to refer to FIGS. 36-42, in this exemplary embodiment, the electronic assembly 72 is a solid state switch used to control one or more electrical loads, such as turning one or more electrical loads “on” or “off” in response to the one or more sensors 50. To turn the electrical load “on,” the exterior surface 20c of the wall plate 20 may be touched causing the electronic assembly 72 to energize one or more electrical relays built into the electronic assembly 72. To turn the electrical load “off,” the exterior surface 20c of the wall plate 20 may be again touched to de-energize the one or more electrical relays built into the electronic assembly 72, as shown in FIGS. 40 and 42. Non-limiting examples of the solid state switch include single pole and three-way switches.
The electronic assembly 72 includes a housing 92 having a body 94 and a cover 96. The cover 96 may be releasably secured to the body 94 using for example a snap fit connection. More specifically, in this exemplary embodiment, the cover 96 includes flexible arms 130 that fit into openings 132 in the body 94 to releasably interlock the body 94 and the cover 96. The electronic assembly 72 includes a printed circuit board (PCB) 98 that is configured and dimensioned to fit within the body 94 of the housing 92. As shown in FIG. 42, the PCB 98 may include the sensor input and signal conditioning circuitry 76 that receives information for one or more sensors 50 and conditions the received information for processing by the controller or signal output circuitry 78. The sensor input and signal conditioning circuitry 76 acts as an interface between the one or more sensors 50 and the electrical wiring device 72 circuitry providing power and analog and digital signals for control and/or operation. The controller or signal output circuitry 78 may output a control signal that drives a power control 79 or may output a 1-24 volt DC or AC electronic control signal that drives various types of electronic devices, such as a 1-24 volt DC or AC electronic lighting control signal. An example of a power control 79 is a HF115F-L 1 pole miniature high power latching relay manufactured by Xiamen Hongfa Electronics Co. However, it is contemplated that a portion of or the complete circuit diagrams shown in FIGS. 7-9 may be utilized in this exemplary embodiment.
Referring to FIGS. 40 and 41, the mounting plate 74 of the device module 70 includes an opening 84 through which the cover 96 of the housing 92 of the electrical wiring device 72 can pass and mounting holes 86 used when attaching the mounting plate 74 to the electrical box 14, similar to the electrical box 14 shown in FIG. 34, using for example fasteners 79. In addition, the mounting plate 74 includes one or more device mounting apertures 81 positioned, for example, around the perimeter of the opening 84 through which fasteners 83 can pass and be threaded into mounting holes, e.g., threaded mounting holes, 97 in the cover of the housing 92 of the electrical wiring device 72 to releasably secure the electrical wiring device 72 to the mounting plate 74. In addition, the seal member 88 forming part of the device module 70 includes an opening 89 through which the cover 96 of the electrical wiring device 72 can pass and mounting holes 87 used when attaching the mounting plate 74 to the electrical box 14. As noted, the seal member 88 may be positioned between the mounting plate 74 and the electrical box 14 to limit and possible prevent moisture from entering the electrical box 14 when the mounting plate 74 is secured to or attached directly to the electrical box 14. A non-limiting example of a seal member 88 is a gasket, such as a neoprene gasket. Thus, when the electrical wiring device 72 is releasably secured to the mounting plate 74, the cover 96 of the electrical wiring device 72 passes through the opening 89 in the seal member 88 and the opening 84 in the mounting plate 74 so that an outer surface of the cover 96 extends past the mounting plate 94 and can be positioned in contact with or in close proximity to the inside surface 20b of the wall plate 20 when the wall plate 20 is attached to the mounting plate 74.
In this exemplary embodiment, the wall plate 20 is mounted to the mounting plate 74 by a snap fit connection. More specifically, the wall plate 20 includes flexible arms 73 that fit over an edge 74c, e.g., a raised edge, of the mounting plate 74 to releasably interlock the wall plate 20 and the mounting plate 74. As noted above, the interior portion of the wall plate 20 may include a cavity 20a having an inside surface 20b, seen in FIG. 41, that is configured and dimensioned to at least receive the cover 96 of the housing 92 of the electrical wiring device 72. Thus, when the mounting plate 74, seen in FIG. 40, is secured to an electrical box 14, and the wall plate 20 is mounted to the mounting plate 74, the cover 96 is positioned in contact with or in close proximity to the inside surface 20b of the wall plate 20. With the cover 96 positioned in contact with or in close proximity to the inside surface 20b of the wall plate 20, the one or more sensors 50 are in position to be activated when the exterior surface 20c is touched as described herein.
It is noted that the device module 70 and/or the faceplate module 12 may be configured to communicate with other devices using, for example, known WiFi, Bluetooth, Zigbee, or other lower energy communication or known near field communication (NFC) technology.
