So I was dusting off a pair of 1122 switches and rewired the controller and got them working beautifully, even at 8VAC from my spare RW 110 watt transformer. Here is where things get interesting - I simply had the switches on the ground connected to the transformer with alligator clips. My freshly (and correctly) wired switch controller was in my hand (not mounted). I tested the functionality of the switches and was very happy at my resurrection job, but every so often when switching the switches, I got a reasonable sized jolt of electron juice from the underside of the controller. The controller does have exposed rivet contacts and so now the real question - are these jolts indicative of the voltage spikes that the TVS are recommended to protect against when operating equipment with electronic circuit boards?
