Choosing an Electrical Switch

High-Current Toggle Switches

Able to withstand high currents, these switches are often used with motors and pumps.

Flush-Mount 22 mm Panel-Mount
Push-Button Switches

Because these switches mount flush against a panel, they're easy to clean and hard to damage.

Flush-Mount 16 mm Panel-Mount
Push-Button Switches

Because these switches mount flush against a panel, they're easy to clean and hard to damage.

10 mm Panel-Mount Push-Button Switches

Install in 10 mm dia. cutouts.

Rocker Switches

Wireless Pendant Switches

Operate equipment from up to 330 feet away—these switches include a transmitter and a receiver that connects to equipment.

Foot Switches

Keep your hands free for other tasks by triggering switches with your foot.

Wireless Foot Switches

Control equipment from up to 40 feet away—these switches include a transmitter and a receiver that connects to equipment.

Any-Direction Foot Switches

Apply pressure from any direction to actuate these switches.

Wet-Location Foot Switches

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

Corrosion-Resistant Washdown Foot Switches

Step on these switches for hands-free actuation in an area with frequent washdowns.

Light Duty Foot Switches

Use this switch for intermittent, light-duty applications.

Hazardous Location Foot Switches

These switches are rated for environments where hazardous material is present.

Variable-Speed Foot Switches

When the pedal is pressed, the built-in potentiometer adjusts the resistance to vary the speed for motor drives.

Outlet-Box-Mount Key Switches

Reset fire panels, or open electromagnetic locks, electric strikes, and automatic door openers. These switches require a key to turn circuits on or off, limiting access and preventing accidental activation.

Two-Hand Safety Switches

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

Enclosure Door Switches

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

Limit Switches

Snap-Acting Switches

Open and close circuits quickly to minimize arcing and prevent contacts from sticking. These switches are often used as door-open indicators on appliances and enclosures.

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.

Mil. Spec. Washdown Snap-Acting Switches

Keep out dirt and moisture—the sealed housing on these switches is watertight and meets MIL-PRF-8805.

Enclosed Wet-Location Snap-Acting Switches

Rated IP67, these switches have an enclosure that shields their interior during temporary submersion. They open and close circuits quickly to prevent arcing and keep contacts from sticking.

Subminiature Snap-Acting Switches

The smallest snap-acting switches we offer, these fit into the tiniest of spaces.

Subminiature Wet-Location Snap-Acting Switches

Built for tight spaces exposed to water, these switches have a housing that's less than 1" long and IP67 rated for protection from temporary submersion.

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.

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.

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 protection from temporary submersion.

Hinge-Actuated Safety Switches

Replace access door hinges with these switches; they actuate when the door opens at least 4°.

Photoelectric Switches

Photoelectric Switches with Relay Output

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

Time-Delay Photoelectric Switches with Relay Output

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

Fiber-Optic Photoelectric Switches

The highly flexible fiber-optic cable and small sensing end help you position these switches in hard to reach areas.

Time-Delay Fiber-Optic Photoelectric Switches

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

Timer Switches

Wall-Mount Timer Switches

Use these switches in place of standard wall switches to automatically turn electrical equipment on or off after a set interval of time.

Panel-Mount Timer Switches

Install these switches in a panel cutout to automatically turn electrical equipment on or off after a set interval.

Surface/DIN-Rail Mount Time
and Day Activated Switches

Mount these switches to a flat surface or attach to DIN rail.

Panel-Mount Time and Day Activated Switches

Install these switches in a panel cutout.

Panel-Mount Set-to-the-Minute
Time and Day Activated Switches
