Choosing an Electrical Switch

Hinge-Actuated Safety Switches

Replace the hinges on access doors or machine guards with these switches to keep your team safe from active machinery.

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. They’re often used with machine guards.

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.

Enclosure Door Switches

Activate or deactivate fans, lights, and other devices inside your enclosure when you open or close the door.

Enclosure Disconnect Switches

Install these switches inside an enclosure to prevent it from opening when power is on—turn the switch to disconnect power and release the door.

Manual Override Enclosure Disconnect Switches

Keep power running while you access your enclosure. Unlike standard enclosure disconnect switches, which shut off power as you open your enclosure, these have an override function.
