Abstract
A latching relay having a manual reset function. The latching relay includes a coil for generating a magnetic force. An armature is provided which is dragged by the magnetic force to change into a first switching state of the armature. An elastic device which is moved following the movement of the armature caused by the magnetic force, is adapted to receive an external force to switch the armature back into a second switching state, wherein the armature can maintain one of the switching states without the magnetic force and the external force existing. A reset device is provided to receive the external force to move the elastic device, thereby switching the armature into the second switching state. A fixed support fixes in place the coil, armature and elastic device and provides a magnetic loop to strengthen the magnetic force.
