    Hi guys,

    I'm in need of a specific switch that will allow the following:

    - The switch needs to have 3 contacts (legs)
    - Switch OFF -> no contact between any of the legs
    - Switch ON -> contact between all of the 3 legs

    I've looked everywhere, but I couldn't find anything that fits.

    Can you advise on a switch that will fit?

    I was wondering, if I take a simple 3 leg on/off rocker switch and connect 2 of the leg with a diode, will it solve it?

    Use any double pole single throw (DPST) switch like this with a jumper permanently attached between the throws (A & C). The three terminals are then A/C, B & D.
