Metal 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 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.

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.

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. All meet EN 60947-5-5 for compliance with European machine directives for emergency stop applications. 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.
When-on illuminated switches light up when you push the button, so you can tell if the power has been cut.
Continuously illuminated switches stay lit once installed for high visibility in dark areas.

30 mm Emergency Stop Panel-Mount Push-Button Switches
Immediately cut power with a single push. These switches are rated for protection from low-pressure streams of water and oil/coolant spraying. They have positive force contacts that will open a circuit when actuated even if a spring fails or the contacts stick. Switches include enough contact blocks to control the number of circuits listed.
Turn twist switches back on by twisting the button and pull switches by pulling it. Add an optional lockout on either kind to cover the button and prevent changes its position.
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.
Additional contact blocks (sold separately) can be added to control more circuits, or to replace the included contact block.

Plastic Emergency Stop Enclosed Push-Button Switches
Rated NEMA 3S, NEMA 4X, NEMA 13, and IP66, these plastic switches resist corrosion better than aluminum switches and withstand washdowns and oil/coolant spraying. Housed in a yellow enclosure for quick identification, they immediately cut power with a single push. They 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.
Key reset switches are keyed alike, so if you buy multiple switches they will all reset with the same key.
Switches with a power indicator alert you from the front and sides when the switch has been actuated.
Switches with a guard prevent accidental actuation. For extra security, lock the button in the off position with a padlock (not included) to stop these switches from being reset or turned on during machine repairs.

Aluminum Emergency Stop Enclosed Push-Button Switches
These aluminum switches are rated NEMA 4, NEMA 13, and IP66 for protection from washdowns and oil/coolant spraying. Housed in a yellow enclosure for quick identification, they immediately cut power with a single push. They meet EN 60947-5-1 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. UL listed and CSA certified, they also meet American and Canadian safety standards. The front of these switches is UL recognized.
Key reset switches stop you from accidentally resetting the switch before you’ve dealt with the emergency. They’re keyed alike, meaning they all open with the same key.
Illuminated switches include a bulb. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.

High-Visibility Plastic Emergency Stop Enclosed Push-Button Switches



A red light flashes when the actuator is pushed, making it easy to see from a distance. These switches immediately cut power with a single push. They're housed in a protective yellow enclosure for quick identification. All have positive force contacts that will open a circuit when actuated even if a spring fails or the contacts stick. They're rated IP65 for protection from water projected by a nozzle.
Note: If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.
Auxiliary contacts allow you to add a signaling device or control another switch.

Outlet-Box-Mount Push-Button Switches

Also known as palm-button switches, these have a large button that makes them easy to use even while wearing gloves. They're rated NEMA 13 and IP65 for protection from oil/coolant spraying and washdowns.
Switches with positive force contacts will open a circuit when actuated even if a spring fails or the contacts stick.
Ring guards (sold separately) protect the actuator and reduce the chance of accidental actuation.

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.

Frame-Mounted Safety Switches

Also known as interlock switches, these ensure the safety of personnel by automatically shutting off power to machinery when an access door opens. Mount the switch to the door frame and mount a key to the door so that the key is inserted into the switch when the door is closed. When the door opens, the key is removed from the switch and the machine shuts down. They’re often used with machine guards.
Style A-F have positive-force, normally closed contacts that will open a circuit when the switch is actuated even if a spring fails or the contacts stick.
IP67 rated switches protect against temporary submersion.
Flexible keys (sold separately) pivot 15° to make it easier to align with the switch during installation.

Medium-Pressure Switches for Air Compressors



- For Use With: Air
- Connection Material: Steel
- Connection: NPT Female
- Switching Current:
Polycarbonate Plastic: 24/24A
Steel Housing: 35/24A - Switching Voltage: 120V AC/240V AC
These switches meet pressure and electrical requirements of air compressors. They electrically activate automated controls or alarms when a set pressure is reached. Switches are double pole, single throw and normally closed (DPST-NC), so they switch two circuits from on to off.
Switches with air exhaust valve let you release the compressed air after use.
