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

Easy-Grip Pendant Switches
With a slim shape, these switches fit comfortably in your hand. Use them with mobile machinery such as cranes, hoists, and trolleys.
Two-speed switches have staged contacts. When you push the button, it will first actuate the slow speed. Continue to push for the additional speed to be actuated.
Switches with mechanical interlock prevent both buttons from operating simultaneously.
NEMA 4X rated switches protect against corrosion.

Cable-Pull Emergency Stop Switches
Immediately cut power by pulling a cable. These switches are often used to turn off production lines and material handling systems in an emergency. All have positive-force, snap-open contacts that open a circuit when actuated, even if a spring fails or the contacts stick. The contacts will remain open until you tension the cable and reset the switch.
Two-direction switches can be used with tension springs (not included) to open contacts and stop machinery if the cable breaks.
Accessory kits (sold separately) simplify the installation of a new switch.
