WHAT IS IT? The Model RSC is a compact safety switch that provides a
positive shut off of dangerous equipment in an emergency or for normal
operation. A cable pulled by endangered personnel actuates it. The output
contacts of the Model RSC can control up to two separate circuits, one for
machinery shutdown and one for an alarm. Two versions of the Model RSC have the built-in advantage of cable break detection. Another version acts as a standard cable pull switch, while a fourth version is a palm button (only) for punch presses and other indoor equipment.
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 - 1993-5.11. This ANSI standard will probably soon become part of the William-Steiger Act of 1970 - the OSHA act.
