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 for large objects.

Combine an actuator and a switch to assemble the exact limit switch you need.

Start or stop equipment after a set number of rotations to avoid over-rotation.

Install these limit switches where changing a battery or routing wires might be difficult—they power themselves when a moving object contacts the actuator.

A sealed actuator prevents these switches from jamming, even when exposed to sand, mud, or dirt. With a slim design, you can stack them together or fit them in tight spaces.

Protect machinery and ensure the safety of personnel—these switches will open the circuit when actuated even if a spring fails or the contacts stick.

Prevent equipment from automatically restarting—these switches must be manually reset each time they're actuated.
