High Voltage Auxiliary Switches, Type FA, Sliding Contact Construction, for Motor-drive Mechanism, Three-position Mechanism, Quick-earthing Switches

Product Overview
FA series auxiliary switch is an improved product for F10 series auxiliary switch. F10 auxiliary switch has the problems of small contact pressure, poor anti-vibration ability and inconsistent on/off angle, FA series auxiliary switch completely solves these problems. FA series auxiliary switches are compact and exquisite, with reliable performance and wider application space. FA series auxiliary switches are suitable for controlling the closing, breaking, interlocking and signal circuits of various high-voltage switch operating mechanisms.
