Computerized Safety Switch
May 31, 2002
The AC PowerKey computerized safety switch eliminates hazards on such potentially dangerous equipment as saws, compactors or metalworking machines. Operators must enter their personal ID number (PIN) on the keypad to switch on the equipment. The equipment is switched off one of three ways: operator enters stop code, idle time exceeds programmed limit, or an overload current is sensed. International Electronics, Inc., Canton, MA.
