I should have mentioned in the original post that the relays that the switch is controlling is two solid state time delay relays from idec.
We have been in contact with idec and the switch manufacturer and they can't figure it out either. Idec says that thier relays would not cause a spike.
We would like to find a murcury tilt switch that would fit this application but have been unable to find one. We are also considering a probe type switch system.
The switch mfgr said that they ran into a similar problem a few years ago but couldn't remember what they did to solve it. The guy that dealt with the problem was not in today but will be back in on Monday. He thinks that they might have installed a varister across the switch or possibly a capacitor. We will be talking to him on Monday.
leespark,
what was your switch controlling? Was it the same as I have described?
