Rocker Switches
The wide surface of these switches makes them easy to press on and off, even if your hands are full and you need to use an elbow. They’re often used as power switches on electronic devices and control panels.
Switches for a 13/16” dia. panel cutout are round, so you can use a drill bit or knockout to install them instead of cutting a rectangular hole.
Illuminated switches are easy to see in dim and dark areas. They come in red and green, so you can color code your set up.
Switches with an on-on position designation alternate power between sets of terminals.
Note: Illuminated switches include a bulb. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed the bulb voltage.
