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.

Cable-Pull Switches
Connect these switches to a cable to control circuits from a distance. They're typically used to turn off production lines and material handling systems. Mount in any position and tug on the cable to send a switching signal. Equipment will not start up again until the switch is manually reset.

Light-Touch Miniature Snap-Acting Switches
Smaller and more sensitive than standard snap-acting switches, these switches fit in tight spaces and actuate from light pressure. Snap-acting switches quickly open or close circuits to reduce arcing and keep contacts from sticking.
Switches with a plunger actuator require a push to activate, similar to a button.
Switches with a lever actuator activate when material moves across the arm, which provides a large actuation area.

Miniature Snap-Acting Switches
Smaller than standard snap-acting switches, these switches trigger actions in tight spaces. They’re used in components as small as computer mice and engine restart switches. They open and close circuits faster than other switches, preventing contacts from sticking by reducing the time that they're near one another. These switches also minimize the chance of arcing, so electricity won’t jump across contacts.
Switches with a plunger actuator send a signal when the actuator is pushed directly downward. They have the smallest actuator of the actuators here, reducing the risk of accidental switching.
Switches with a lever actuator have a larger surface area than switches with a plunger actuator and can be pushed down by front-to-back movement, so they require less precision to activate.
Switches with a roller lever actuator combine the larger actuation area of a standard lever with a smooth gliding roller actuator. They minimize friction to limit wear and tear on your switch.
Switches with a push-button actuator stick out more than switches with a plunger actuator, so they’re easier to activate.
