    Hello all,

    I'm trying to build a simple circuit in which an (already functioning) radio has a momentary switch built-in. I'm looking for a slimline button-cell type of switch such as this tactile switch.

    My question regarding the above switch for example is: why are there four contact leads on it? Would this switch only have an on/off position? And how would I wire this in? Any help would be greatly appreciated.

    Thank you,
    Bernie

    Hello,

    The switch has two pairs of pins connected to each other.
    Between these pairs the switch is made.
    See the PDF for more info.

    Thanks for the prompt response, bertus!

    I'm relatively new to circuitry and was wondering:

    Does this mean I need to split my wire and have a positive end with two leads and a negative with two leads that each connect to two of the terminals on the switch? Or can I get away with making contact to just two of the terminals?

    Hello,

    As the leads are connected internaly in the switch, only one is needed.

    See the picture I made:
