Bob:
When I first installed the ComTek RCB-5 remote switch on my tower, I had
to change twice all the LEDs on the indoor control box. Over a period of a few
weeks in late summer, I lost all five a couple of times, probably due to
lightning nearby. (No station damage, so my working assumption is a strike
around me.)
I simply installed 0.001 uF bypass caps from the +12VDC lead feeding each
LED to ground. Haven't had a failure since (2001.)
The fellow from whom I purchased the switch had also installed a series of
MOVs on a screw barrier strip inside his switch enclosure out at his tower. I
can't recall what type they were, but I expect that a 50V or lower MOV should
suffice for your app.
