101 Products

Electrical Switching and Controlling

Mil. Spec. Washdown Toggle Switches

These switches meet MIL-S-3950.

High-Current Toggle Switches

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

Wireless Pendant Switches

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

Wireless Foot Switches

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

Enclosure Door Switches

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

Frame-Mounted Safety Switches

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

Compact Spade-Terminal Relays

Smaller than standard spade-terminal relays in height and depth, these relays save space inside your control cabinet.

Enclosed Medium-Current Relays

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

Thin Signal Relays with PLC Protection and Socket

Prevent voltage spikes from damaging your programmable logic controller or other sensitive control device. Thinner than other signal relays, these fit in tight spaces.

Socket-Mount Timer Relays

Plug these timer relays into relay sockets for fast installation and replacement.

Surface-Mount Timer Relays

Use the mounting hole to attach these relays to a flat surface.

Compact Programmable Logic Controllers

Smaller than other PLCs, these controllers save space in your control cabinet. They combine the functionality of a relay, timer relay, and switch in one unit, so you can program simple automation jobs.
