FK10-11 High Voltage Auxiliary Contact

FK10 series auxiliary switches are mainly used in the auxiliary electrical circuits of AC and DC vacuum contactors as control conversion circuits, and can also be used as auxiliary contacts in other electrical appliances, electromagnetic switches, and contactors. Since the contacts of the switch are isolated from the outside world, it can be used normally in dusty environments.
