Prevent accidental actuation from bumps—these switches require you to grip and twist the lever to turn the switch. The contact block and actuator are all one piece, so they won’t separate in high-vibration applications. Install them in a standard panel cutout.

To prevent accidental actuation and limit access to sensitive equipment, these switches require a key to turn circuits on or off. The contact block and actuator are all one piece, so they won’t separate in high-vibration applications. Install them in a standard panel cutout. They’re keyed alike, so they will all open with the same key.

Combine a switch with a thermal overload element to build a starter that can handle high-current-rated motors. All are housed in a durable steel enclosure. They’re also known as NEMA starters.

Thermal overload elements shut motors off if current exceeds the full-load current rating. Three elements are required. To Order: Please specify the full-load current rating of your motor. If the full-load current rating is not shown on the motor’s faceplate, estimate the current rating (given the motor’s power and voltage).

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.

Control cranes and other mobile machinery in dirty, outdoor, and wet environments without damaging your switch. The polycarbonate housing is rated NEMA 4X to protect the switch interior from dust, sprayed water, and ice. They are also rated NEMA 12 for keeping out oil and other liquid drips. All of these switches can be wired to prevent two buttons from operating at the same time.
