Auxiliary Switch High Voltage Switch Silver Contact Mounting Accessories PC Material

FB series auxiliary switch is one of the supporting components of high-voltage complete sets of equipment, which is suitable for controlling the closing, breaking, interlocking and signal circuits of various high-voltage switch operating mechanisms, and can also be used as changeover or combination switch. Its large capacity overcomes the defects of other auxiliary switches with limited capacity and low contact life, and its service life is significantly extended, making it an effective substitute for other similar auxiliary switches.
