Yeah, that's what I was thinking too. The only power to the relay
should be on one of the switched terminals, but not on the coil
circuit. So in order for it to be a problem with the relay, it would
have to be buzzing from the voltage on the circuit it is switching,
because there wouldn't be power at any of the other terminals.
Anything is possible, I suppose. :-)
