Model PC
WHAT IS IT? The Model PC is a rugged safety switch that provides a quick positive shut off of dangerous equipment in emergencies or normal operation. It is actuated by cable pulled by endangered personnel. The output contacts of the Model PC can control up to two separate circuits, one for machinery shutdown and one for alarm.
WHY IS IT NECESSARY? Safety minded operators of conveyors, production lines, elevator equipment, assembly lines, material handling systems, cranes, etc. consider it a must for employee protection. Most states have safety statutes that require these switches on conveyors and related equipment. American National Standard Institute recommends their use in ANSI standard No. ASME B20.1 - 2012-5.11. This ANSI standard will probably soon become part of the William-Steiger Act of 1970- the OSHA act.
