I want to replace the wall-mounted toggle switches that control overhead lighting in several rooms of my house with switches than can be actuated remotely over a CAN bus. What kind of switching element is appropriate for this task? The overhead lights controlled by these switches range from incandescents to LEDs. The largest arrangement is in the main living room and consists of ten incadescent floods totaling about 600w. Other rooms have LED floods totaling about 100w per room. Dimming would be desirable, but not mandatory. I'm in the U.S., so the voltage is 120v 60Hz AC.
I plan to design a small PCB that will have a microcontroller, CAN transceiver, and the switching element. I'm not sure yet whether to supply power to these units as DC over the CAT-5 I plan to run to each outlet (for the CAN signals) or tap it from the AC line. In any case, I want the PCB to be small enough to mount in a standard size wall switch receptacle housing.
