The Leviton signal bridge can be seen at the SmartHome site at
And then a diagram of how it hooks up is at
although I don't understand all the connections. This is more than a
single capacitor, no? And at $42.30, it's sure an expensive cap! (But
only $29.99 if you buy 50 or more...)
Here's one solution I used in the garage:
I don't like leaving the power on to my compressor, thinking that if one of
the lines ever blew a leak while I was away the compressor would run
continuously until it burned up. And it's in an inaccessible corner of the
garage so it's a pain to head over and check whether the switch is off or
on every time I leave.
So I use an X10 module (heavy duty) for the compressor and another module
set to the same address for my radio. A remote switch by the door turns
them both on, so if I can hear the radio, the compressor is energized.
By the way, I don't think you can get the heavy-duty modules from X10.com;
you have to go to X-10 Pro (www.x10pro.com) to get the 220V stuff.
