I have a very basic question. The switch in  question burnt out so I obtained a replacement. For the life of me I can't  figure out which wire goes where. I have three wires, power and feeds to the  Landing and Taxi lights. The switch has four connectors marked H,R,A, B.   The case is marked 600 and is a pull switch with two positions.

 Can anyone help? I am aware it is not RV related.  When I'm not flying my RV4 I have the Cessna to take pictures etc.

    It has been a VERY long time since I've seen these

    switches installed on the Cessnas but if it's a

    4-terminal switch I suspect that an ohmmeter test

    will show that with the switch has no connections

    with the handle all the way in.



    With the handle pulled to the first notch, I think

    the pair of terminals furthest from the panel will

    be connected to each other. This pair is the taxi

    light circuit. With the handle all the way out, the

    pair of terminals closest to the panel will be connected

    to turn on the landing light. In this position, the

    taxi light will be out. Here's an exemplar 4-terminal

    push-pull switch from Cole-Hersee
