Choosing an Electrical Switch

Plastic Enclosed Push-Button Switches

Rated NEMA 4X and 13, all switches resist corrosion and can withstand washdowns and oil/coolant spraying.

Stainless Steel Enclosed Push-Button Switches

With a stainless steel enclosure, these switches are more durable than aluminum and plastic. They're rated NEMA 4X for protection from corrosion and washdowns.

Aluminum Enclosed Push-Button Switches

More lightweight than steel or stainless steel, these aluminum enclosed switches are rated NEMA 4X for protection from corrosion and washdowns.

Under-Mount Enclosed Push-Button Switches

Keep a switch within reach—but not in the way. These mount to the underside of desks, tables, and shelves to keep work surfaces clear and reduce the risk of accidental presses.

Plastic Emergency Stop
Enclosed Push-Button Switches

Rated NEMA 3S, NEMA 4X, NEMA 13, and IP66, these plastic switches resist corrosion better than aluminum switches and withstand washdowns and oil/coolant spraying.

Aluminum Emergency Stop
Enclosed Push-Button Switches

These aluminum switches are rated NEMA 4, NEMA 13, and IP66 for protection from washdowns and oil/coolant spraying.

High-Visibility Plastic Emergency
Stop Enclosed Push-Button Switches

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.

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.

Plastic Enclosed Lever Switches

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

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.

Hazardous Location Cable-Pull
Emergency Stop Switches

Safe to use near ignitable gases and dust, the housing on these switches seals in anything that could ignite flammable material. Yank the cable anywhere along your line to quickly cut power in emergencies.

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.

Disconnect Switches

Enclosed Compact Disconnect Switches

Small yet mighty, these switches are about as tall and wide as an index card yet durable enough to mount directly to a wall.

Washdown Enclosed Disconnect Switches

The IP66 rated housing not only shields these switches from washdowns but also makes them durable enough to be mounted outside of an electrical panel.

Enclosed Disconnect Switches

Cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance. These switches are housed in a protective enclosure that resists denting, chipping, and cracking.

Hazardous Location Enclosed Disconnect Switches

With a housing that’s designed to contain an explosion, these switches are safe to use in areas where ignitable concentrations of flammable or combustible gas, dust, or fibers may be present.

Durable Disconnect Switches

Protected by a steel enclosure, these switches withstand tougher conditions than switches in a plastic housing. Also known as safety switches, they have quick-make/quick-break action to eliminate arcing and prolong switch life.

Outdoor Durable Disconnect Switches

A raintight NEMA 3R rated enclosure protects these switches outdoors.

Transfer Switches

Manual Transfer Switches

If there’s a power outage, flip the toggle for each circuit on these switches to backup power.

Automatic Transfer Switches

When the microcontroller inside detects a power outage, these switches automatically fire up a backup generator. They’ll switch back to utility power once power is restored.
