How you wire a iii-prong rocker switch depends on whether information technology is illuminated with an LED or neon seedling, or whether it is an SPST (unmarried-pole, unmarried-throw) or an SPDT (single-pole, double-throw) switch. If you don't know what kind of switch it is, a meter that tests resistance tin can tell you. It can also assistance you decide which prong goes to the switch bulb ground and which prong switches the device you are turning on or off. On all rockers, the center prong attaches to the power source.
Examine all surfaces of the switch, especially the sides and the metal terminals. Wiring schematics are frequently etched or molded to the plastic body. If at that place is no schematic on the switch, look for stamped numbers or letters (1, 2 ,3 or A, B, C) on or near the terminals themselves. If a printed sail came with the switch, use the terminal stamps with any possible printed schematics.
Use an Ohm meter or multimeter to identify switch poles if no marking or documentation exists. Set the meter to resistance and turn information technology on. Touch the black and cherry-red examination leads together and employ the pollex wheel to zilch the meter. If it is digital, it will autoset.
Hold one meter pb to the center pole on the switch. Hold the other to an stop pole -- information technology doesn't matter which one. Note the reading on the meter. Flick the switch and notation what happens. If there is no change in the meter reading, the cease pole you are testing is bulb ground. If the meter swings to zero, that pole will connect to the device you lot are controlling with the switch and you can wire the switch only ane way. If the meter swings to zero on either cease pole, you have an SPDT switch, which changes power over from 1 device to another.
Drill a hole to mountain the switch, or employ a plastic-cut saw bit to cut a rectangular switch pigsty. Run all switch wiring through the hole.
Strip i/2-inch insulation off the ends of all wires you are connecting to the switch. Insert the end of the wire going to the ability feed through the hole in the eye pole. Insert the wire connecting to the switched device through the switched final. Insert the ground wire through the ground terminal. The other end of the ground lead is wired to common vehicle basis. If the switch is an SPDT with 3 poles, there is no indicator lamp within the switch. On three-pole SPST rockers, the ground atomic number 82 grounds the indicator lamp but.
Snap the switch torso into the hole, indicator lamp pointing upwards.
