    Hi Mike, the key switch is approximately 23mm in length including the two pins on the bottom, 15mm in width with the NUT and 10mm in width without the nut. The top of the switch is around 4mm thick and 15mm in width.

    A: I don?t know which circuit you have but you just connect the two terminals on the switch as you would with a standard push to make switch. When the key is turned one way the switch closes when it is turned the other way the switch opens.
