Plastic 22 mm Emergency Stop Panel-Mount Push-Button Switches
Immediately cut power with a single push. These switches meet EN 418 for compliance with European machine directives for emergency stop applications. All have positive force contacts that will open a circuit when actuated even if a spring fails or the contacts stick. They're rated IP66, IP69K, NEMA 3S, NEMA 4X, and NEMA 13, and are UL and C-UL Recognized Components. Switches include enough contact blocks to control the number of circuits listed. Contact blocks are rated IP20 and are UL and C-UL Listed.
Key reset switches are keyed alike, so if you buy multiple switches they will all reset with the same key.
Additional contact blocks (sold separately) can be added to control more circuits, or replace the included contact block.

All have positive force contacts that will open a circuit when actuated even if a spring fails or the contacts stick. They include enough contact blocks to control the number of circuits listed.
Pull reset, illuminated pull reset, and turn reset switches are rated NEMA 4, 13, and IP66. Contact blocks for these switches are rated IP20.
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.
Pull reset switches with lockout latch when you depress the button, and can be locked in that position using a padlock with a max. 3/16" shackle diameter. Switches are rated NEMA 13 and IP65.
Additional contact blocks (sold separately) can be added to control more circuits, or replace the included contact block.

Make or break an electrical circuit. These contact blocks mount to manual switches and transmit an electrical signal when the switch actuator is engaged. You can stack multiple blocks, so a single switch can control several circuits. This is helpful in setups that require multiple systems to turn on or off at the same time. For example, the switch on a conveyor line could turn off the conveyor and turn on a diverter and alarm.
16 mm Emergency Stop Panel-Mount Push-Button Switches
Immediately cut power with a single push. These switches meet EN 418 for compliance with European machine directives for emergency stop applications. They're rated NEMA 4, 13, and IP65 for protection from washdowns and oil/coolant spraying.
Key reset switches are keyed alike, so if you buy multiple switches they will all reset with the same key.

Plastic Emergency Stop Enclosed Push-Button Switches
Made of yellow polycarbonate plastic, these enclosed switches are easy to see and resist dents, chips, and cracks. They are more corrosion resistant than aluminum enclosed switches and withstand washdowns and oil/coolant spraying. Mount them to a wall or attach a cord grip to position them at your workstation. They have positive force contacts that will open a circuit when actuated, even if a spring fails or the contacts stick. A single push will immediately cut power.
The switches can be reset by manually pulling, turning or unlocking them by key. Key reset switches are keyed alike, so if you buy multiple switches, they will all reset with the same key.
Switches with a guard prevent accidental actuation. To stop the switches from being reset or turned on during machine repairs, lock the guard with a padlock.
Switches with a power indicator alert you from the front and sides when the switch has been actuated.
