Switches

Hinge-Actuated Safety Switches

Replace access door hinges with these switches; they actuate when the door opens at least 4°.

Access-Delay Frame-Mounted Safety Switches

Delay access to hazardous areas until conditions are safe; use these switches with machines that take time to stop after they are turned off. They mount to a door frame.

Frame-Mounted Safety Switches

Often used with machine guards, these switches mount to a door frame.

Outlet-Box-Mount Key Switches

Reset fire panels, or open electromagnetic locks, electric strikes, and automatic door openers. These switches require a key to turn circuits on or off, limiting access and preventing accidental activation.

Enclosure Disconnect Switches

Mount these switches inside your enclosure to prevent it from opening when power is on—actuating the switch disconnects power and releases the door.
