Technical Field

[0001] The utility model relates to the technical field of magnetic latching vacuum relay equipment, in particular to a medium wave magnetic latching vacuum relay which is easy to replace. Background Art

[0002] The magnetic latching relay is a new type of relay developed in recent years. It is a type of automatic switch. Similar to traditional electromagnetic relays, magnetic latching relays can also automatically connect and disconnect circuits. However, the normally closed or normally open state of the magnetic latching relay is not maintained by electromagnetic force, but completely depends on the action of permanent magnets. The switching state conversion is completed by triggering a pulse electrical signal of a certain width.

[0003] The magnetic latching vacuum relay in the prior art needs to remove multiple screws each time when it is installed and disassembled, which is quite troublesome. In view of the above problem, a magnetic latching vacuum relay for medium wave that is easy to replace is provided. Utility Model Content
