DESCRIPTION
GE Interlogix Industrial Key-Operated Safety Switches with Solenoid Release utilize a removable stainless steel key to provide a positive means of turning the control power off should an access panel, door, gate, guard, etc. be opened during machine operation. Prime candidates for this series of safety switches are equipment that cannot be shutdown in mid cycle, machines that have large mechanical inertia, high temperatures or other areas that cannot be immediately entered. There are two versions of the Key-Operated Safety Switch with Solenoid Release, Series “D” (de-energized) and “E” (energized). With the key removed, access is allowed through the guard, gate, etc., to be opened. Since the safety switch contacts can only be closed when the key is installed in the switch, the machine cannot be restarted until the guard, gate, etc., is closed. This re-establishes the protection around the machine. The Series “D” switch locks in the key when the solenoid is “de-energized” (without power).
