Heavy Duty Limit Switches

Heavy Duty Limit Switches

Use these limit switches in areas where dust, dirt, sand, and other loose particles may build up and jam limit switches, such as foundries and mills. The shaft extends away from the switch case to allow more space for particles to fall through rather than build up.

Pin Plunger

These switches are actuated when force is applied perpendicular to the pin at the end of the plunger.

Roller Plunger

As the roller travels along a surface and force is applied, the force is translated from the roller to the plunger, which actuates the switch.

Roller Lever

Choose a roller lever when the switch setup involves radial movement rather than linear movement. A roller on the lever reduces friction, which means less force is required to actuate the switch. When force is removed, the lever springs back to its original position.

Adjustable Roller Lever

Adjust the position of the roller lever along the side of the arm for various switch setups. A roller on the lever reduces friction, which means less force is required to actuate the switch. When force is removed, the lever springs back to its original position.

Rod Lever

Longer than roller levers but with the same radial actuation capability, these rod levers are useful when additional reach is needed.

Wobble Stick

Also known as a flexible rod, spring rod, or cat whiskers, wobble sticks have a similar length as rod levers but can flex in any direction for full 360° capability.
