Choosing an Electrical Switch

Limit Switches
Often used on conveyor systems and bin filling operations, 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. All are rated IP67 and NEMA 13 for protection from corrosion, oil/coolant spraying, and temporary submersion.
Styles D and E have an actuator that allows you to adjust its height, making it easier to align switch with the target during installation.

Low-Profile Wet-Location 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. 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.
Switches with powder-coated zinc and plastic housings are rated NEMA 4 and 13 for protection from washdowns and oil/coolant spraying.

Corrosion-Resistant Washdown Limit Switches
Rated NEMA 6P, 13, and IP67, these switches are protected from corrosion, oil/coolant spraying, washdowns, and temporary submersion. 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 bin filling operations.
Styles D and E have an actuator that allows you to adjust its height, making it easier to align switch with the target during installation.
Switches with wire leads are rated NEMA 3S and IP69K and protected from rain, snow and sleet, and from high temperature, high pressure jets of water.

Sealed Wet-Location Limit Switches
Sealed actuators prevent these switches from jamming, even when exposed to sand, mud, or dirt. They're rated IP67 for temporary submersion. They have a slim design and can be stacked together or fit into narrow spaces. 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.
Switches with powder-coated zinc and plastic housings are rated NEMA 4 and 13 for protection from washdowns and oil/coolant spraying.

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. 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 bin filling operations. All are NEMA and IP rated for protection from washdowns.
Styles E and F have an actuator that allows you to adjust its height, making it easier to align switch with the target during installation.
NEMA 13 and IP67 rated switches are protected from oil/coolant spraying and temporary submersion.

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.
Switches with a plunger actuator let you adjust the actuator’s height to easily align it with your target. They require a push to activate, similar to a button.
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.
