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.

Contact Blocks for Manual Switches
Make or break an electrical circuit. These contact blocks mount to manual switches and transmit an electrical signal when the switch actuator is engaged. You can stack multiple blocks, so a single switch can control several circuits. This is helpful in setups that require multiple systems to turn on or off at the same time. For example, the switch on a conveyor line could turn off the conveyor and turn on a diverter and alarm.

Easy-Grip Pendant Switches
With a slim shape, these switches fit comfortably in your hand. Use them with mobile machinery such as cranes, hoists, and trolleys.
Switches with mechanical interlock prevent both buttons from operating simultaneously.
NEMA 4X rated switches protect against corrosion.

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.

Limit Switches
When a moving object contacts the actuator on these switches, they open or close a circuit. They have the rapid-closing action of a snap-acting switch, but with a larger actuator. This makes them a good choice for use with large objects—for instance, a box on a conveyor runs into the switch, stopping the conveyor.
Switches with a T-rod actuator have four rods extending in different directions from a pivot point. If an object contacts any of the rods from any direction, these switches actuate. Since they have such a large actuation area, they’re great for detecting moving parts when your machine tool isn’t perfectly aligned.
