Safety Switches
Key Operated • Solenoid Release

Non-Metallic Housing
The Advance Controls’ Key Operated Safety Switch with Solenoid Release utilizes a solenoid and removable stainless steel key to provide a positive means to turn "Off" control power should an access panel, door, gate, guard, etc. be opened. The switch denies access to the controlled area until the operator electrically releases the key, thus protecting areas where access must be strictly controlled. Examples are equipment that has a large mechanical inertia, high temperature, cannot stop in mid cycle, other areas that cannot be immediately entered or where the machine cycle cannot be interrupted. Since the safety switch contacts can be closed only when the key is installed in the switch, the machine cannot be restarted until the door, gate, guard, etc., is closed, thus re-establishing the protection around the machine.

Solenoid Operated Contacts: Solenoid releases Key and transfers certain contacts.

Key Operated Contacts: Solenoid releases Key - Key transfers certain contacts.
