    I have a rocker switch and I can get it to work as a switch, but it's
    supposed to illuminate and I'm at a complete loss...

    It has 3 prongs on the bottom which are labelled on the switch as 1,2,
    and 3

    1 and 2 I've found are connected to the switch. when the switch is off
    they're open, and when the switch is on they conduct.

    3 doesnt seem to be connected to either of the other prongs no matter
    which position the switch is in... I've tried using dc and ac voltages
    on this 3rd prong to get the switch to light up but I can't get
    anything to work...

    the only other thing written on the case is 'canal b series'. a google
    search didn't help :-/

    if you need any other info just let me know and I'll try to get
    whatever you need

    ** You did not look very hard:

    These are for AC power mains only.

    The third terminal is an AC neutral link for the neon lamp - which may run
    from 120 or 240 volts AC.

    Most likely a 120/240 volt AC switch.
    the third leg needs to be on the ground/neutral side.

    if the light stays on at all times, just rotate 1,2 connection.
    I think 1 is the Line , 2 is the load and 3 is the common/N et.c.

    worth a try I guess."

    It's probably a neon that needs tying to AC neutral.
