WD-40 can be wicked stuff. A friend that uses it on everything had me look at the 2-way radio on his boat when it stopped working. He finally admitted to spraying WD-40 under the faceplate to lubricate the volume control when it started sticking. It fixed the sticking problem, but insulated the wipe pad on the potentiometer so that it was open (infinite resistance). I would expect the same results with relays and switches. Cleaning with acetone got rid of the residue.
