Product overview
FA series auxiliary switch is an improved product for F10 series auxiliary switch. F10 auxiliary switch has the problems of low contact pressure, poor seismic capacity and inconsistent on-off angle. FA series auxiliary switch completely solves these problems. FA series auxiliary switch is small and exquisite, reliable performance, more extensive application space. FA series auxiliary switches are suitable for controlling closing, opening, interlocking and signal circuits of various high-voltage switch operating mechanisms.
