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.

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.

Compact Safety Limit Switches

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

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.

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.

Snap-Acting Switches

Open and close circuits in a snap. These switches actuate quickly to minimize arcing and prevent contacts from sticking.

Enclosed Washdown Snap-Acting Switches

Rated NEMA 4 , these enclosed switches have a sealed actuator for protection from washdowns.

Enclosed Snap-Acting Switches

Enclosures protect these snap-acting switches from the environment.

Light-Touch Subminiature Snap-Acting Switches

Actuate these switches with a fraction of the force of other subminiature switches for increased responsiveness. Among the smallest snap-acting switches we offer, they fit into the tiniest of spaces.

Miniature Snap-Acting Switches

Smaller than standard size snap-acting switches, these fit in tight spaces.

Ultra-Miniature Snap-Acting Switches

Trigger actions in devices as small as phones and drones. The smallest snap-acting switches we offer, these switches fit into the tiniest of spaces and help keep weight to a minimum.

Proximity Switches

DC Metallic-Object Proximity Switches

These switches use DC input voltage and produce PNP or NPN signal output. They're often used with programmable logic controllers (PLCs).

Slot DC Metallic-Object Proximity Switches

These inductive proximity switches sense metallic objects each time they pass through the slot, even when they’re obscured by water, oil, dirt, or a surface finish. Use them to measure the speed of rotating equipment and to count or detect moving objects, such as sheet metal being fed into a stamping process.

Hazardous Location Slot DC
Metallic-Object Proximity Switches

For use in volatile areas, these intrinsically safe switches detect objects when they pass through the slot. They use a NAMUR signal to operate at a low current and voltage, so they won’t ignite or create sparks. ATEX and IECEx certified, they protect against explosion.

Hazardous Location DC
Metallic-Object Proximity Switches

Use these switches to sense metallic objects in environments containing flammable gases and combustible dust. ATEX and IECEx certified to protect against explosion, they produce a low-current, low-voltage NAMUR signal, so they won’t ignite or create sparks.

Hazardous Location Flat-Body DC
Metallic-Object Proximity Switches

Mount these intrinsically safe switches to flat surfaces in volatile areas. Their low-current, low-voltage NAMUR signal means they won’t ignite or create sparks while in use. ATEX and IECEx certified, they meet international standards to protect against explosion where combustible dust and flammable gases are present.

Hazardous Location Ring DC
Metallic-Object Proximity Switches

These intrinsically safe switches detect objects as they’re routed through the ring. They produce a low-current, low-voltage NAMUR signal, so they won’t ignite or create sparks. Switches are ATEX certified to protect against explosion.

AC/DC Metallic-Object Proximity Switches

Switches accept both AC and DC input voltage.

AC Metallic-Object Proximity Switches

Most often found in older devices, these switches require AC input voltage.

Flat-Body AC/DC Metallic-Object Proximity Switches

Mount these flat inductive switches to a base or rail to remotely detect metallic objects in wet and dirty environments.

DC Universal-Object Proximity Switches

Often used with programmable logic controllers (PLCs), these switches use DC input voltage and produce PNP or NPN signal output.

Hazardous Location DC
Universal-Object Proximity Switches

These switches use a NAMUR signal to operate at a low current and voltage, so they won’t ignite or produce sparks. ATEX certified, they protect against explosion in environments containing flammable gases and combustible dust. Switches sense both metallic and nonmetallic objects.

Valve Position Switches

These switches sense when a valve is open or closed, supporting flow and temperature control within your system and offering reliable feedback.

Hazardous Location Valve Position Switches

Support flow and temperature control in your system with these intrinsically safe switches, which sense when a valve is open or closed in volatile areas. They are ATEX and IECEx certified to protect against explosion.

Snap-Action Thermostats

Also known as snap discs, these thermostats switch on cooling systems or switch off heating systems when equipment gets too hot.
