Safety Switches
Key Operated - Metal and Non Metallic Housing

Advance Controls' Key Operated Safety Switches are designed to provide a positive means of turning the control power in the equipment "Off" should an access panel, door, guard, etc. be opened during operation. Unlike a simple limit, or reed type switch, the key operated Safety Switch requires a special design stainless steel key to operate the switch. By requiring this special key, the switch cannot be easily defeated, tied down, or bypassed by using simple hand tools. Removing the special key from the switch positively switches the safety contacts. The head of the switch can be rotated in 4 - 90 degree steps allowing entrance from any one of 8 different positions. This allows the switch to be mounted in a variety of different configurations. These features make the key operated Safety Switch an acceptable recognized safety switch for worldwide applications.

Ordering Information
Switches are furnished standard with a 90 degree mounting key. Other key styles are available. See Accessories for
FX, FR and FD series switches.
