Choosing an Electrical Switch

Metal 22 mm Panel-Mount Push-Button Switches

Plastic 22 mm Panel-Mount Push-Button Switches

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.

Space Saver 22 mm Panel-Mount Push-Button Switches

The built-in contact block in these switches extends behind the panel half the depth of most other 22 mm switches, saving valuable space.

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

Plastic 22 mm Emergency Stop
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.

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 22 mm Panel-Mount Lever Switches

Switches are rated NEMA 4, 13, and IP66.

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.

22 mm Panel-Mount Key Switches

Sized for 22 mm dia. panel cutouts, these switches require a key to turn circuits on or off, limiting access to sensitive equipment.

Finger-Touch Switches

The light touch of a finger turns circuits on and off without pressing down a contact.

Fingerprint Switches

Use fingerprints to confirm the identity of personnel before granting access to secure areas or equipment.

Joystick Switches

Grab these switches by hand and pivot them to use.

22 mm Panel-Mount Knob Switches

Turn these switches by hand.

Harsh Environment Panel-Mount Disconnect Switches

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

Harsh Environment Potentiometers

Rated NEMA 4X and 13, these potentiometers are protected from debris, washdowns, and oil/coolant spraying.

Hand-Operated Air Directional Control Valves

Two-Speed Two-Action Air Directional Control Valves

Often used to extend and then retract a cylinder at different speeds, these valves create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. Also known as 4-way and 5/2 valves.

Single-Action Air Directional Control Valves

Create one action with these valves, such as extending a cylinder.
