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.

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.

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.

Lock out the on/off or emergency-stop buttons on machinery to prevent accidental or unauthorized startups, such as during maintenance. These lockout covers secure with padlocks and indicate to workers that a button is off for safety. By disabling push buttons, these safety covers also help you comply with OSHA 29 CFR 1910.147 lockout requirements for maintaining machinery.

Removable safety covers twist on and off a mounted base that fits around a button. Use the included colored labels to identify the buttons. Red covers are easy to see when installed.

Hinged safety covers have a door that flips shut. They mount permanently and encase two button sizes—22 mm or 30 mm. Snap off the tabs around the mounting hole to fit 30 mm buttons.

Crossbar safety covers have a bar that locks a button in the off position.

Often used to house emergency-stop buttons, switches, and lights, these bright yellow enclosures are easy to spot, even in dimly lit areas. All have standard-size push-button holes to save time—no need to measure and cut your own holes.

Rated IP66 and IP68, all of these enclosures protect contents from dust, high-pressure washdowns, and submersion in water. Those with a NEMA 6P and NEMA 12 rating also guard contents from corrosion, oil, and the weather.

House emergency stop buttons, life safety equipment, and other devices that need to be seen with these brightly colored enclosures, which are easy to spot even in high-dust areas. Made of polycarbonate, they resist denting, cracking, and chipping as well as fading from UV rays. They’re rust resistant, and more chemical resistant than fiberglass and metal enclosures. These enclosures don’t block wireless or radio signals, so they’re good for use with Wi-Fi-enabled components

Add panels as interior mounting surfaces that don’t require you drilling holes in your enclosure’s wall and compromising its environmental rating. Use them as a surface for assembling electronics outside the enclosure, then install them when work is finished.
