We have a VP-50 controller in our RV-4 that has worked great since installed. Last week we flew to Abilene TX from Phoenix for LOE. We had some heavy bumps the last few hundred miles in Texas. Twice I looked down to see that the Avionics power switch and the Alt switch on the VP switch panel had turned off. I can only guess that the bumps overcame the internal resistance in the switches and they went down as a result of the bumps. So I am wondering now if the switches have weakened from constant use. Has anyone else had this problem?
