AI Technical Summary
Existing magnetic latching relays cannot achieve separate on/off switching without affecting each other when two or more relays need to be used simultaneously, and they also occupy a large space and have a high cost.
Design a magnetic latching relay, in which the housing is divided into two chambers by a partition, and a first electromagnetic component and a second electromagnetic component are respectively installed, while sharing a common stationary contact, so as to realize independent control and simultaneous control.
This allows two relays to be switched on and off independently without affecting each other, reducing space requirements and lowering costs.
