Snap-Acting Switches

Open and close circuits in a snap. These switches actuate quickly to minimize arcing and prevent contacts from sticking. They’re often used to indicate that an appliance or enclosure door is open. You can also use them inside limit, pressure, and temperature switches.
Switches with a wobble stick actuator have a flexible arm that can actuate from any direction.

Limit Switches

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. 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 wobble stick actuator have an arm that rotates 360°, so you don’t need to align it in a specific direction. Since the actuator is flexible, it won’t snap if pushed backward. That makes these switches a great choice for systems that get jammed often.
Switches rated NEMA 13 are protected against dirt and oil/coolant spraying. Switches rated IP67 are protected against dust and temporary submersion.

Build-Your-Own Limit Switches
Combine an actuator and a switch to assemble the exact limit switch you need. 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 for conveyor systems and elevators. Each actuator style is compatible with all housing styles and vice versa.
Wobble stick actuators open or close circuits when an object hits the flexible arm. The arm has a 360° range of motion, so it can be actuated from any direction. This means that if there’s a jam, these switches are less likely to break than switches that are aligned to a specific direction.

Low-Profile Limit Switches

Stack these slim switches together, or fit them into tight spaces. They're rated IP67 for protection from temporary submersion. 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 have a larger actuator for large objects. They’re often used on conveyor systems and elevators.

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.

Compact Safety Limit Switches

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 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.

Hazardous Location Limit Switches

Safely open or close a circuit near ignitable gases and dust—the housing on these switches seals in anything that could ignite flammable material. You'll know they're safe because they're NEC Class I, Division 1, Groups B, C, and D; and Class II, Division 1, Groups E, F, and G certified for hazardous locations. These switches 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.
