F1-4 type auxiliary switchDetailed product description：

1、 Main purpose
The F1-4 auxiliary switch is mainly used in operating mechanisms such as high-voltage circuit breakers, high and low isolation switches, low-voltage air switches, and low-voltage knife switches. It is used as an auxiliary electrical device to connect or disconnect signal control measurement, protection, and interlocking line devices.

2、 Applicable working conditions:
1. The temperature of the surrounding medium is not higher than+40 ℃ and not lower than -40 ℃
2. Altitude not exceeding 3000 meters
3. At a temperature of+25 ℃, the relative humidity of the air should not exceed 90%
4. In places without severe vibration and oscillation
5. A gas environment with no explosion hazard, no conductive dust, no damage to insulation, and no corrosion of metals in the surrounding medium.

3、 Structural form:
1. F1 can adjust the rotation angle of the center moving contact according to different requirements, which can be divided into 60 °~90 °~120 °
2. F1 can be divided into horizontal and vertical installation methods, and into horizontal with fast mechanism and direct drive and delay contact according to structure.
