About Electrical Switches

Choose a switch with the right trigger type, number of inputs, and control functions to power your equipment.

Vibration-Resistant Plastic 22 mm Panel-Mount Push-Button-Actuator Emergency Stop Switches

A single-piece construction prevents the contact block from separating from the actuator in high-vibration applications. These switches immediately cut power with a single push. They have positive force contacts that will open a circuit when actuated even if a spring fails or the contacts stick. These switches meet American, Canadian, European, and other global safety requirements. They’re rated NEMA 4X, NEMA 13, and IP65 for protection from corrosion, washdowns, and oil/coolant spraying.

Note: Illuminated switches include a bulb. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.

Continuous—Continuously illuminated switches stay lit once installed for high visibility in dark areas.

Labels for Emergency Stop Switches


With Keyway Notch	Without Keyway

Stick these labels to your control board to make it easy to find the stop switch in an emergency. Unlike legend plates, they’ll stay in place even if they don't exactly match the panel cutout for your switch.

Choose a label with a panel cutout diameter that’s equal to or larger than the diameter of your cutout or switch housing. If you’re unsure whether the keyway will fit, choose the next larger diameter.

Vibration-Resistant 22 mm Panel-Mount Lever Switches

Prevent accidental actuation from bumps—these switches require you to grip and twist the lever to turn the switch. The contact block and actuator are all one piece, so they won’t separate in high-vibration applications. Install them in a standard panel cutout.

Vibration-Resistant 22 mm Panel-Mount Key Switches

To prevent accidental actuation and limit access to sensitive equipment, these switches require a key to turn circuits on or off. The contact block and actuator are all one piece, so they won’t separate in high-vibration applications. Install them in a standard panel cutout. They’re keyed alike, so they will all open with the same key.
