Choosing an Electrical Switch

Toggle Switches

Wet-Location Toggle Switches

A rubber seal protects these switches from splashing water.

Mil. Spec. Washdown Toggle Switches

These switches meet MIL-S-3950.

Miniature Toggle Switches

Maximize the space in a panel—these switches are half the size of most toggle switches.

DIN-Rail Mount Miniature Toggle Switches

Built into a terminal block, these switches mount to DIN rail.

High-Current Toggle Switches

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

Pull-to-Unlock Toggle Switches

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

Plastic 22 mm Panel-Mount Push-Button 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.

Metal Premium 30 mm
Panel-Mount Push-Button Switches

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

30 mm Emergency Stop
Panel-Mount Push-Button Switches

Immediately cut power with a single push.

30 mm Multifunction Panel-Mount Push-Button Switches

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

Miniature Panel-Mount Push-Button Switches

Sized for 4 mm or 6 mm panel cutouts, these switches are often used with circuit boards to control electronics.

Rocker Switches

Design-Your-Own Rocker Switches

Choose from a variety of messages and colored lenses to combine a rocker with a base and wiring socket for a complete switch.

High-Starting-Current Rocker Switches

Also known as high-inrush current switches, these switches can handle starting currents up to 10 times greater than their rating, such as when a motor starts.

High-Current Rocker Switches

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

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.

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.

16 mm Panel-Mount Lever Switches

Install in 16 mm dia. cutouts.

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

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

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

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

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

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

Slide Switches

Cable-Pull Emergency Stop Switches

Immediately cut power by pulling the cable.

3/4" Panel-Mount Key Switches

Install these key switches in 3/4" dia. panel cutouts. They require a key to turn circuits on or off, limiting access to sensitive equipment.

16 mm Panel-Mount Key Switches

These 16 mm switches require a key to turn circuits on or off, limiting access to sensitive equipment.

Foot Switches

Press these switches with your foot for convenient, hands-free operation.

Wet-Location Foot Switches

Safe for use in wet locations, these switches are IP and NEMA rated for protection from corrosion, washdowns, and oil/coolant spraying.

Corrosion-Resistant Washdown Foot Switches

Rated NEMA 6P, 13, and IP68, these switches protect against corrosion, washdowns, and temporary submersion.

22 mm Panel-Mount Knob Switches

Turn these switches by hand.

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.

Hinge-Actuated Safety Switches

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

Frame-Mounted Safety Switches

Often used with machine guards, these switches mount to a door frame.

Access-Delay Frame-Mounted Safety Switches

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.

Disconnect Switches

Panel-Mount Disconnect Switches

Harsh Environment Panel-Mount Disconnect Switches

Rated IP69K, these switches are protected from high-pressure and high-temperature washdowns.

Enclosed Disconnect Switches

Washdown Enclosed Disconnect Switches

Rated IP66, these switches are protected from washdowns.

Enclosure Disconnect Switches

Mount these switches inside your enclosure to prevent it from opening when power is on—actuating the switch disconnects power and releases the door.

DIN-Rail Mount Ethernet Switches

Mount these Ethernet switches to DIN rail to bring connections closer to where you need them.

Relays

With no moving parts, these solid state relays have an extended service life. Mount them directly to DIN rail.

Enclosed Medium-Current Relays

The built-in enclosure protects contacts from dust and dirt.

Medium-Current Relays

These relays are rated for motors with 1-3 horsepower or 15-90 amps—use them with industrial automation systems, security and emergency lighting, and small motors. Also known as power relays.

DIN-Rail Mount Long-Life Medium-Current Relays

Mount these relays directly to DIN rail.

Long-Life Medium-Current Relays

With no moving parts, these solid state medium-current relays have an extended service life.

Sequenced Latching Relays

These relays switch through a series of different circuit configurations every time they receive an input voltage. Also known as step relays.
