Ⅰ、Applications
1、Smart meters;
2、Concentrated meter reading system;
3、Street lamp control system;
4、Compound switch;
5、Automatic control device/assembly.


Ⅱ、Operating system
Magnetic Latching Relay is a kink of high-power relay, of which the contact 
condition is maintained by the magnetic force from permanent magnet. When the load 
need to be open or closed, positive and negative dc impulse voltage will drive 
the coil,so that relay can complete the state transition between opening and closing 
instantly. And then, the coil doesn’t need electricity any more, only by the magnetic 
force of permanent magnet, its condition can be maintained.
