FK10 series auxiliary switch is mainly used for control conversion circuit in auxiliary electric circuit of AC DC vacuum contactor, and can also be used as auxiliary contact in other electrical appliances, electromagnetic switches and contactors. Since the contacts of the switch are isolated from the outside, they can be used normally in dusty environments. The FK10 series auxiliary switch can be customized with a set of contacts with delay.
FK10 series Auxiliary switch and auxiliary contact is applies to AC vacuum contactor, solenoid switch, VCB, etc. high and low voltage switchgear, interlocked with mechanisms for indication, signaling, and control.
