Product Introduction
The FA series auxiliary switches are improved products for the F10 series auxiliary switches. The F10 auxiliary switches have problems such as low contact pressure, poor shock resistance and unstable on-off.
The FA series auxiliary switches have completely solved these problems.
The FA series auxiliary switches are compact, exquisite, reliable in performance and have a wider range of applications.
The FA series auxiliary switches are suitable for controlling the closing, opening, interlocking and signal circuits of various high-voltage switch operating mechanisms.

Environmental conditions
1、Ambient air temperature: -40℃ to +70℃;
2. Altitude: No more than 5,000 meters;
3. Humidity: The average relative humidity within 24 hours shall not exceed 95%. The average pressure of water vapor does not exceed 2.2kPa. The monthly average relative humidity shall not exceed 90%. The average pressure of water vapor does not exceed 1.8kPa.
4. The vibration acceleration shall not exceed 15m/s².
5. The surrounding air is not obviously polluted by dust, smoke, corrosive or flammable gases.
Working principle
The FA series auxiliary switches feature an indirect drive structure. The rotation of the square shaft drives the rotation of the moving contact piece, causing it to move. The electrical circuit is controlled by the connection or disconnection of the moving and fixed contact pieces.
