Also known as interlock switches, these ensure the safety of personnel by automatically shutting off power to machinery when an access door opens. They’re often used with machine guards.

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.

Our most sensitive limit switches, these switches actuate with the slightest push for a high degree of accuracy.

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

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

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.

Secure these switches into panel cutouts using mounting nuts. They have a slim body so they can also be stacked together or fit into tight spaces.

Open and close circuits in a snap—even in harsh conditions. With a rubber-encased housing and stainless steel bracket, these switches handle high vibrations and resist corrosion. They’re rated IP68 for protection from dust and temporary submersion.

Rated NEMA 4 , these enclosed switches have a sealed actuator for protection from washdowns.

Keep out dirt and moisture—the sealed housing on these switches is watertight and meets MIL-PRF-8805.

Built for tight spaces exposed to water, these switches have a housing that's less than 1" long and IP67 rated for protection from temporary submersion.

At least 25% smaller than our Miniature Snap-Acting Switches, these switches are often used to trigger actions from inside a vehicle’s door or an engine compartment.
