Sears/Craftsman used to market a 3 way switch for controlling a 120VAC load
that was triggered by a garage door opener. Mine failed and attempts to
debug/repair it have been less than fruitful. It appears as though there
are multiple problems with the original unit. I used it to control a 500W
spotlight for my driveway/parking area. I cannot seem to locate anything on
the market today other than a plug-in, 1 way switch that operates from a
common garage door opener signal. I miss the convenience and would like to
make one on my own. Basically, the Sears unit utilized a couple of
internally triggered triacs switched by a 4013 and an Rx module to change
the state of the flip-flop. Other ancillary items on the board merely
stepped down the mains voltage to power the Rx module and logic and there
are also a half dozen or so small transistors and an inductive coil that my
lack of knowledge prevents me from understanding. Question: Any web
reference(s) out there that would get me started designing and assembling
such a device and perhaps take me right through to completion? I'm sure
thousands of people out there could draw just what I need on a napkin in
less than a minute. TIA.
