Choosing an Electrical Switch

Frame-Mounted Safety Switches

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.

Manual-Reset Safety Limit Switches

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

Heavy Duty Limit Switches

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

Build-Your-Own Limit Switches

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

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.

Magnetically Actuated Switches

Tamper-Resistant Magnetically Actuated Switches

Prevent unauthorized use—these switches require coded magnets to actuate. They cannot be bypassed using ordinary magnets.

Tamper-Resistant Magnetic Contact Alarm Switches

Prevent unauthorized use of doors or windows with a combination of coded magnets and contacts that wire to an alarm system.

Manual Switches

Vibration-Resistant Plastic 22 mm Emergency
Stop Panel-Mount Push-Button Switches

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

High-Visibility Plastic 22 mm Emergency
Stop Panel-Mount Push-Button Switches

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

Metal 22 mm Emergency Stop
Panel-Mount Push-Button Switches

Metal 22 mm Panel-Mount Push-Button Switches

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

Plastic 22 mm Panel-Mount Push-Button Switches

A quick push is all it takes to actuate these switches.

30 mm Emergency Stop
Panel-Mount Push-Button Switches

Immediately cut power with a single push.

Hazardous Location 30 mm Emergency
Stop Panel-Mount Push-Button Switches

Use these switches where ignitable gas and dust may be present. Their contact blocks are UL listed for Class I, Division 2, Groups B, C, and D hazardous locations.

30 mm Multifunction Panel-Mount
Push-Button Switches

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

Metal 30 mm Panel-Mount Push-Button Switches

Metal Premium 30 mm
Panel-Mount Push-Button Switches

More durable than standard metal switches, these can handle tough, repetitive use.

Plastic 30 mm Panel-Mount Push-Button Switches

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

Hazardous Location 30 mm
Panel-Mount Push-Button Switches

Actuate these switches with a quick push. A housing seals in anything that could ignite flammable material, so you can use them where ignitable gas and dust may be present.

Flush-Mount 30 mm Panel-Mount
Push-Button Switches

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

Plastic Emergency Stop
Enclosed Push-Button Switches

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.

Hazardous Location Enclosed Push-Button Switches

Use these switches where ignitable gas and dust may be present. They're rated for use in hazardous locations.

Emergency Stop Outlet-Box-Mount
Push-Button Switches

Immediately cut power with a single push.

Outlet-Box-Mount Push-Button Switches

Mount these switches in an outlet box. Also known as palm-button switches, they have a large button that makes them easy to use even while wearing gloves.

Handle Push-Button Switches

Save space in your setup—these switches double as handles on machines and equipment.

Two-Hand Safety Switches

It takes two hands to activate these switches, minimizing the risk of accidental equipment start up.

Cable-Pull Emergency Stop Switches

Immediately cut power by pulling the cable.

Overhead Rope-Pull Switches

Tug the hanging rope to actuate these switches.

Enclosure Door Switches

Activate or deactivate fans, lights, and other devices inside your enclosure when you open or close the door.

22 mm Panel-Mount Knob Switches

Turn these switches by hand.

Easy-Grip Pendant Switches

With a slim shape, these switches fit comfortably in your hand.

Hazardous Location Enclosed Lever Switches

Use these switches where ignitable gas, dust, and fibers may be present. They're UL and C-UL listed for hazardous locations.

Plastic Enclosed Lever Switches

The enclosure not only protects these switches, but also adds options for how you install them.

22 mm Panel-Mount Build-Your-Own Metal Switches

Choose an actuator and contact block to make your own 22 mm metal switch.

22 mm Panel-Mount
Build-Your-Own Plastic Switches

Choose an actuator and contact block to make your own 22 mm plastic switch.

16 mm Panel-Mount
Build-Your-Own Plastic Switches

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

30 mm Panel-Mount Build-Your-Own Metal Switches

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

Plastic 22 mm Panel-Mount Lever Switches

These switches are protected from corrosion, high-temperature and high-pressure washdowns, and oil/coolant spraying. Install them in 22 mm dia. cutouts.

Vibration-Resistant 22 mm
Panel-Mount Lever Switches

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.

Metal 30 mm Panel-Mount Lever Switches

Rated NEMA 4, 13, and IP66, these metal switches are protected from washdowns and oil/coolant spraying. Install them in 30 mm dia. cutouts.

Metal 22 mm Panel-Mount Lever Switches

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.

Plastic 30 mm Panel-Mount Lever Switches

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.

30 mm Panel-Mount Key Switches

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.

Hazardous Location 30 mm
Panel-Mount Key Switches

Designed for use near ignitable gases, fibers, and dust, these switches have a housing that seals in anything that could ignite flammable material. They require a key to turn circuits on or off, preventing accidental activation and limiting access.
