The fields such as electric appliance are one of most important control elements.Relay just develops towards miniaturization and energy-saving direction.Magnetic keep after
Electric appliance provides magnetic force using permanent magnet, and contact acts when energized, and after coil removes excitation, contact still maintains the shape
State.Magnetic latching relay is a kind of energy-saving and environment-friendly relay.
Relay contact state retention force is generated by magnet steel, and the magnetic flux that magnet steel generates is formed by armature, iron core, yoke
Closed circuit generates suction in armature and yoke interpolar, and armature applies thrust to movable contact spring, makes to generate enough between dynamic and static contact
Pressure, can reliable current-carrying.When needing disconnects relay contact, need to only it apply enough width-pulse to coil
Voltage, the flow direction that the magnetic flux and magnet steel which generates generate on magnetic pole on the contrary, will generate identical as magnet steel
Polarity thrust can be generated between armature and yoke magnetic pole according to magnetic field principle of same-sex repulsion, when magnetic circuit generate resultant moment
The countertorque of size reed, armature part rotate around the axis, relay off-state；It, must be online if returning to closed state
Apply an opposite pulse on circle.
