Safety Stop Control

Click image to enlarge
Model RS

WHAT IS IT? The Model RS is a heavy-duty safety control ("stop switch") that provides a positive shut off of dangerous equipment in an emergency. A cable pulled by endangered personnel actuates the control. The output contacts of the Model RS-2 can control up to two separate circuits, one for machinery shutdown and one for an 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.
