22 mm Panel-Mount Build-Your-Own Plastic Switches
Choose an actuator and contact block to make your own switch. Actuators are rated NEMA 3S, 4X and 13 for protection from dust, outdoor environments, corrosion, oil, and washdowns. Use legend plates (not included) to label switches. BACO Controls switches are only compatible with BACO manufactured legend plates.

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.
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.

Push Button Safety Covers
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.
