Vibration-Resistant 22 mm Panel-Mount Lever Switches
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.

Vibration-Resistant 22 mm Panel-Mount Key Switches
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.
