    hi,
    The letters L N and Load usually apply to mains wiring connections.?
    When you say 12V DC , is that the control voltage input.

    Post a part number or link.

    this is an extremely very simple on off switch it came from overseas so there's not a part number that I can find. Its made for 12 volts for light LED lighting and what not.

    Generally a simple contact closure switch that is marked that way is one that has an internal on/off indicator light/led.
    If it is a solid state switch then the load terminal could be a NPN or PNP open collector.
    Max.
