Also known as interlock switches, these ensure the safety of personnel by automatically shutting off power to machinery when an access door opens. They’re often used with machine guards.

Delay access to hazardous areas until conditions are safe; use these switches with machines that take time to stop after they are turned off. They mount to a door frame.

Block access to machinery while it's running. These safety switches link to a single actuator, so no other RFID tag or card can interfere.

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.

Prevent equipment from automatically restarting—these switches must be manually reset each time they're actuated.

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

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

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

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.

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

Prevent automatic doors from closing on a person or an object—these switches immediately turn machinery off when actuated with minimal force.

These switches actuate when a magnet comes within sensing distance, and reset when the magnet moves away.

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

Turn the face on these switches to sense metallic objects from the front, sides, top, or bottom.

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.

Sense objects as they pass through the switch’s ring via tubing or a funnel. These switches are often used to monitor blockages, detect breaks in spooling wire, or count small metallic parts, such as screws, during the stamping process.

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.

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.

Rotate the face on these switches five different directions for easy installation and positioning—they work with both AC and DC inputs.

With a narrow, flat body, these switches fit in tight spaces.

A built-in relay produces AC voltage output. These switches are often used with older programmable logic controllers (PLCs).

Set these switches to delay activation by up to fifteen seconds after detecting an object.

Rated IP69K, these switches can withstand high-pressure, high-temperature washdowns and temporary submersion.

A slim design and a light beam that’s angled upwards allow these switches to sense objects from between conveyor rollers.

Monitor a wide area around dangerous machinery. If a person or object gets too close, these scanners signal your relay or controller to either trigger a warning or shut down the machinery.

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.

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

Immediately cut power by pulling the cable.

Connect these switches to a cable to control circuits from a distance. They're typically used to turn off production lines and material handling systems.

Prevent accidental actuation—these toggle switches must be pulled up before they can switch a circuit.

A single-piece construction prevents the contact block from separating from the actuator in high-vibration applications.

A base that lights up draws attention to emergency stops. When pushed, these switches immediately cut power.

Simple to use, these switches actuate with a quick push.

A housing seals in anything that could ignite flammable material, so you can use these switches where explosive gas, dust, and fibers may be. They actuate with a quick push.

Mount these switches in panel cutouts where changing a battery or routing wires might be difficult—they power themselves when you push the button.

Immediately cut power with a single push.

Save space on a panel by using one switch to perform multiple switching functions.

Push the button to actuate these switches. Colored actuators help you tell switches apart without reading labels.

Actuate these switches with the push of a button. Their buttons are distinct colors to help you quickly spot switches without labels.

The face of these switches mounts flush against a panel, so they're easy to clean and hard to damage.

Install in 14 mm dia. cutouts.

Made of yellow polycarbonate plastic, these enclosed switches are easy to see and resist dents, chips, and cracks. They are more corrosion resistant than aluminum enclosed switches and withstand washdowns and oil/coolant spraying.

A red light flashes when the actuator is pushed, making it easy to see from a distance. They're rated IP65 for protection from washdowns.

A lightweight yet durable alternative to stainless steel enclosed switches, these aluminum enclosed switches withstand corrosion, oil, and washdowns.

Immediately cut power with a single push.

Clip these switches onto nearby structures made from T-slotted framing to quickly cut power with the push of a button.

These familiar push-button switches mount to flat surfaces.

Choose an actuator and contact block to make your own 30 mm switch.

Choose an actuator and contact block to make your own 16 mm switch.

An infrared light beam senses the lightest finger contact to switch a circuit on or off.

The light touch of a finger turns circuits on and off without pressing down a contact. Program these switches to fit your application—control their color, pattern, and sensitivity.

Grip and twist a lever to turn these switches on or off—they’re designed to prevent accidental actuation. Install them into standard-sized panel cutouts.

Prevent accidental actuation from bumps or vibration—these switches require you to grip and twist the lever to turn the switch. The contact block and actuator are all one piece, so they won’t separate in high-vibration applications.

Prevent accidental actuation from bumps or jostles—these switches require you grip and twist a lever to turn them on or off. Install them in 30 mm dia. cutouts.

Made for areas where ignitable gas and vapor may be present, these switches have a housing that seals in anything that could spark flammable material.

Operate these switches hands-free when working in damp or humid environments.

Also known as deadman switches, these switches make sure equipment only runs if you lightly press the hand grip. If you let go or a shock tightens your grip, they cut power.

Control cranes and other mobile machinery in dirty, outdoor, and wet environments without damaging your switch.

Sized for 22 mm dia. panel cutouts, these switches require a key to turn circuits on or off, limiting access to sensitive equipment.

Install these key switches in 30 mm dia. panel cutouts. They require a key to turn circuits on or off, limiting access to sensitive equipment.
