Product overview
FK series auxiliary switches are one of the supporting components for high-voltage switchgear. They are a new type of auxiliary switch developed to meet the current usage requirements of auxiliary switches in the power industry. Compared with commonly used auxiliary switches such as F6 and F9, their angle control is more flexible, enabling various special switching operations. Compared with F10 auxiliary switches, their contact capacity has more than doubled, which can better meet the high current demands of the high-voltage switch industry. They are widely applicable for controlling the closing, opening, interlocking, and signal circuits of various high-voltage switch operating mechanisms, and can also be used as transfer or combination switches.
