Protect machinery and ensure the safety of personnel—these switches have positive-force contacts that will open the circuit when actuated even if a spring fails or the contacts stick. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. These switches 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 roller lever actuator use a lever with a roller at the end to activate. This allows parts to glide across the actuation surface with minimal friction, limiting wear and tear on your switch.

Switches with a rod actuator use a rod extending out of the body to actuate, so they’ll activate even if an object is far away.

Styles D, E, and F have an actuator that allows you to adjust its height, making it easier to align switch with the target during installation.

Switches with a steel actuator are more durable than switches with a plastic actuator. They also handle higher loads.

Switches with a plastic actuator limit wear and tear on passing objects better than switches with a steel actuator.
