My Fuel Pump switch is a DPST toggle switch. The one circuit on there runs the idiot light, and the other pulls the VP-X circuit for the pump down to ground to turn it ON. Over the last couple of years I have had the switch occasionally not work to make the pump turn on. The idiot light on the panel will light up, but no sound from the pump. Using the VP-X menu on the Dynon EFIS you can alternatively get the pump turned on. If I get my hand behind the panel and wiggle the connectors back there, it will usually come back to life and work fine. I had every intention of swapping out the toggle switch at this annual, but when I was under the panel I realized that I only had a spare SPST switch, so I figured I'd do the swap at some other point later on.
Today, I went out for a quick flight and for the first time, the wiggling of the connector did pretty much nothing. I guess the switch finally is kaput! Thankfully, the VP-X menu can run the pump ON/OFF (but no idiot light when it is ON). Looks like an order to SteinAir is needed!
I'm just curious as to what the MTBF might be on this toggle switch. These are the good quality Carling switches from Stein, so I would have thought these would last forever.
Anyone else had a toggle switch go flaky at 660 hours?
