Shorter and thinner than other safety limit switches, these are sized to fit tight spaces. They protect machinery and ensure the safety of personnel. Positive-force contacts open the circuit when actuated, even if a spring fails or the contacts stick. They send a signal to your circuit when an object hits the actuator—for instance, a box on a conveyor runs into the switch, stopping the conveyor. They open and close circuits as fast as snap-acting switches, but they have a bigger actuator for large objects. All are NEMA and IP rated for protection from washdowns.

Switches with a plunger actuator require a push to activate, similar to a button.

Switches with a roller plunger actuator have a roller that moves parallel to the mounting direction when an object pushes the actuator. This reduces friction during actuation to limit wear and tear.

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.

Switches with a rod actuator have a large actuation area with a rod extending out of the actuator’s body. They’re best where the object actuating the switch is far away.

Switches with a wobble stick actuator have an arm that rotates 360°, so you don’t need to align it in a specific direction. The actuator won’t snap if pushed backward, such as if there’s a jam in your system.

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

NEMA 13 and IP67 rated switches are protected from oil/coolant spraying and temporary submersion.
