A sealed actuator prevents these switches from jamming, even when exposed to sand, mud, or dirt. They're also rated IP67 for temporary submersion. With a slim design, you can stack them or fit them in tight spaces. 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 plunger actuator require a push to actuate, similar to a button.

Switches with a roller plunger or cross roller plunger actuator have a roller that moves when an object pushes the actuator. This reduces friction during actuation to limit wear and tear on your switch. On cross roller plungers, the roller moves perpendicular to the mounting direction.

Switches with a 4-pole micro M12 plug connect to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.

Switches with a powder-coated zinc or plastic housing are rated NEMA 4 and 13 for protection from washdowns and oil/coolant spraying.

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. These switches have the rapid-closing action of a snap-acting switch, but have a larger actuator for large objects. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. They’re often used on conveyor systems and elevators. All are rated IP67 for protection from temporary submersion. They have a 4-pole micro M12 plug that connects to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.

Plunger actuators open or close circuits when objects push against them.

Roller-plunger actuators open or close circuits when an object pushes against the roller, which moves the plunger. The roller moves parallel to the mounting direction, so it helps push the plunger even if the force isn’t straight on. The roller also reduces friction during actuation which prevents wear and tear over time.

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.
