FC series auxiliary switch is one of the auxiliary components of high voltage equipment. It adopts CAM structure and magnetic blowout mode. It has the characteristics of diversified and flexible CAM switch contacts, and it also has the function of expanding the number of contacts that ordinary CAM switches do not have.
The contact part of FC series auxiliary switch adopts the advanced permanent magnet magnetic blow-out mode, which inhibits the arc generation when breaking the circuit, greatly enhances the breaking ability of the contact, and solves the problem that the auxiliary switch is difficult to break the direct current in the industry. The magnetic field is generated by a permanent magnet with high magnetic field strength, which ensures the stability and permanence of the magnetic field. It is suitable for controlling the closing, opening, interlocking and signal loop of various high-voltage switch operating mechanisms, and can also be used as a conversion or combination switch.
