Choosing an Electrical Switch

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 for large objects.

Build-Your-Own Limit Switches

Combine an actuator and a switch to assemble the exact limit switch you need.

Rotary Limit Switches

Start or stop equipment after a set number of rotations to avoid over-rotation.

Heavy Duty Limit Switches

Rugged enough for mining operations, these limit switches require a high actuation force, like heavy rocks moving on a conveyor.

Panel-Mount Sealed Wet-Location Limit Switches

Sealed actuators prevent these switches from jamming, even when exposed to oil, sand, mud, or ice.

Wireless Self-Powered Limit Switches

Install these limit switches where changing a battery or routing wires might be difficult—they power themselves when a moving object contacts the actuator.

Safety Limit Switches

Protect machinery and ensure the safety of personnel—these switches will open the circuit when actuated even if a spring fails or the contacts stick.

Compact Safety Limit Switches

Shorter and thinner than other safety limit switches, these are sized to fit tight spaces.

Low-Profile Limit Switches

Stack these slim switches together, or fit them into tight spaces. They're rated IP67 for protection from temporary submersion.

Sealed Low-Profile Limit Switches

A sealed actuator prevents these switches from jamming, even when exposed to sand, mud, or dirt. With a slim design, you can stack them together or fit them in tight spaces.

Panel-Mount Low-Profile Limit Switches

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.

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.

Washdown Limit Switches

Rated NEMA 3S and IP69K, these switches can handle washdowns with high pressures and temperatures. They’re also protected from oil/coolant spraying, precipitation, and temporary submersion.
