  1. Hello group,

    I have a toggle switch DPDT, and a plan to make some wiring.

    My question is : with 2 ON position for the toggle switch, how do I find
    which side is wich ? From what I could find on the web, on DOWN position, I
    will have 2-3 and 5-6 connected, and with UP position, I will have 2-1 and
    5-4. What will tell me where is DOWN, and where is UP . I don't see anything
    on the switch, except a small plate that says 6V 125VAC, and on the other
    side, an other plate that says MTS-2.

    This is probably a stupid question for most of you, but I would appreciate
    help from anyone.

  3. The two center terminals are the moving contacts, and they normally
    connect to the terminals opposite the handle position. That is, if
    you hold the switch so the handle moves vertically, and the handle is
    down, connections will be made between the center and top terminals.

    You could always test with an ohmmeter to confirm this.

    If you do not have a continuity tester or an ohm meter, the lamp and a
    battery from a flashlight and some wire and you can build a simple circuit
    to test the continuity.
  5. Generally, with a toggle switch, the center set of pins will connect
    to the pins on the opposite side of the switch lever's
    position...YMMV. As others suggest, do a continuity test.

  6. Thank you to John, Peter and Tom and celstuff

    with toggle switches typically the pins furthest from the handle are
    connected, but they aren't all like that.

    hook it up to a battery and a small light bulb. and test it out for yourself.
