    4 Pin Switch Video

    Pins 1 and 2 are connected together.

    Pins 3 and 4 are connected together and the switch action is between these pairs of pins.

    To get a switch action you need to connect one side of your circuit to pins 1,2 and the other side to pins 3,4.

    Of course, you do not have to connect both pins on each side of the switch. It will work by connecting 1 and 3 or 2 and 3 etc.

    But this still doesn’t answer WHICH pin

    So I grabbed my multimeter.

    When the button is not pressed, 1 and 2 are electrically connected with (zero resistance).

    But when the button is pressed, 1 and 2 and 4 electrically connected.
