I have a rocker switch from ebay: http://www.ebay.com/itm/110682551682?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
but the problem is that theres no information on how to hook it up. I asked the seller and he didn't know himself. Here's what the listing says:
Size 1 1/4 inch hi x 1 inch wide x 1 3/8 deep
Lug type terminals
Built in light (light lits when switch is in the on position).
Marked on the rocker: I/O (on off) for precise indications
Rated at 15A 250V AC (20A 125V)
Snaps in to a rectangular hole
My problem is that the rocker switch has 4 terminals. I'm assuming 2 terminals for the mains, and 2 for the light bulb inside. How do I know which one is which, or can I assume that the light bulb inside is also 110 volts?
