My RV-12 has removable wings. There are limit switches on the 2 pins that lock the wings in place.
Originally the limit switches were wired to a form C relay. If the relay was energized, the start circuit was enabled.
If the relay was not energized, the start circuit was disabled and the normally closed relay contacts turned on a LED warning light.
Not satisfied with leaving well enough alone, I replaced the relay with MOSFET transistors. Below is a picture of the circuit.

After posting the schematic, I realized that the 2K2 resistor on the right side is not needed.
