Frame-Mounted Safety Switches
Key Shown Actuating from the Side
D
Also known as interlock switches, these ensure the safety of personnel by automatically shutting off power to machinery when an access door opens. Mount the switch to the door frame and mount the key to the door so that the key is inserted into the switch when the door is closed. When the door opens, the key is removed from the switch and the machine shuts down. Keys actuate from both the top and the side of the switch. They’re often used with machine guards. All have positive-force, normally closed contacts that will open a circuit when the switch is actuated even if a spring fails or the contacts stick. They’re NEMA and IP rated for protection from washdowns.
NEMA 6 and IP67 rated switches protect against temporary submersion.
Adjustable-mount keys (sold separately) are compatible with Style D. They pivot 15° to make it easier to align with the switch during installation.
