Install these switches in areas with oil, coolant, corrosive chemicals, and regular washdowns. They're rated IP69K and NEMA 4X and 12 or 12K. Since they’re already protected inside a housing, you can mount them to a wall if there’s no space left in your electrical panel. You need to grip and twist the lever to actuate, so they won’t accidentally turn on or off if something bumps into them. To lock them in the off position, attach a padlock (not included) to the lever. Use these switches to turn motors on and off, or with other circuits such as lighting and electric heat circuits. They do not provide overload protection.

Switches with a plastic housing can be turned into a handheld control for moving around your workstation by attaching a cord and cord grip. The housing is PBT polyester, so it won’t swell in moist environments.

Switches with a power indicator use LED lights to show the status of power flowing into the switch and power flowing from the switch to your motor. This can help you check for issues, such as a welded contact or phase loss, without having to open the housing.
