F10 series auxiliary switch is mainly used as the signal control and interlocking protection contact in the control circuit of various high-voltage circuit breakers and high-voltage disconnecting switch operating mechanism for breaking and closing, and can also be used as transfer switch and combination switch. It has been widely used in the secondary circuit of VS1 (ZN63), ZN12, 3AF, ZN65, FZN25, CT19, CT19, CTD and other vacuum circuit breakers, load switches and spring-operated mechanisms.
The F10 auxiliary switch is a rotary auxiliary switch, and the lead-out terminal is connected with a fully insulated terminal. The contact is in flat sliding contact, and the moving contact is composed of two contact pieces, with no fixed gap and no contact seat, so the contact pressure of each pair of contacts can be consistent. This product is assembled from modular switch units, and the number of contact sections can be arbitrarily determined according to user requirements. The whole switch is small in size, simple in structure, flexible in operation, safe and reliable
