Type RTS Test Switches are designed to simplify and speed testing and check-out of relay, control and instrumentation systems. They eliminate the need to change connections and prevent open-circuiting CTs during tests. Featured is a unique arrangement of stationary and sliding contacts in a well insulated glass-filled polycarbonate body. RTS switches are essentially double-pole, double-throw switches operated by push-pull knob. Multiple switches made up of two to four units operated by a single shaft and knob are available in several arrangements.
