IP40 magnetic blowing micro switch high voltage switch for rail transit sterling silver contact PC shell

Product Details

FK series auxiliary switch is one of the supporting components of high-voltage complete sets of equipment. It is a new type of auxiliary switch developed according to the current use requirements of auxiliary switches in the power industry. Compared with commonly used auxiliary switches such as F6 and F9, its angle control is more flexible and various special switching can be realized. Compared with F10 auxiliary switch, the contact capacity is more than doubled, which can better meet the high-current demand of high-voltage switch industry. It is more widely used to control the closing, opening, interlocking and signal circuits of various high-voltage switch operating mechanisms, and can also be used as a conversion or combination switch.
