I had a similar problem with mine (the key would actually FALL OUT)
in flight and it would appear to be in the OFF position and still
leave one MAG hot. I just replaced the blasted thing. A new bendix
switch wasn't that much. My ignition key didn't match the canopy
or baggage compartment locks anyhow.

Now, for the real question:

Do I have to get this part from Piper (for big $$$), or can I use the
(apparently identical) switch shown in the Aircraft Spruce catalog?
