Emergency Stop Outlet-Box-Mount Push-Button Switches
Immediately cut power with a single push. The large palm-sized buttons on these switches provide an easy target, so they're easy to use even while wearing gloves. When the button is depressed, the switch latches and can be locked in that position using a lockout or padlock with a 9/32” shackle diameter (not included). All have positive force contacts that will open the circuit when actuated even if a spring fails or the contacts stick. They're rated NEMA 13 and IP65 for protection from oil/coolant spraying and washdowns.

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. Mount them in a standard panel cutout.
Switches with lockout latch when you depress the button and can be locked in that position using a lockout or padlock with a 9/32" shackle diameter.
Illuminated switches are visible in low light. They include a bulb. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.
Turn twist switches back on by twisting the button and pull switches by pulling it. Add an optional lockout (sold separately) on either kind to cover the button and prevent changes to its position.
Additional contact blocks (sold separately) can be added to control more circuits or replace the included contact blocks.

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.
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.
