Abstract
The utility model discloses a toggle switch with power failure protection function, which comprises a main body, a contact assembly installed on the main body, a power failure protection electromagnetic assembly, a button installed on the main body and a locking mechanism which locks the button. The locking mechanism comprises a locking piece installed on the button and a tripping piece which is matched with the locking piece and installed on the main body. The electromagnetic assembly comprises an electromagnetic coil, an armature and a pullback spring which pulls the armature. Part of the tripping piece is matched with the armature, and the tripping piece pushes the armature to move towards the electromagnetic coil, or the armature pushes the tripping piece to disengage with the locking piece. The tripping piece presses a yoke under the drive of the button to drive the armature to rotate to approach the electromagnetic assembly so as to reduce the attraction of the electromagnetic assembly. In this way, the power of the electromagnetic assembly is reduced, and meanwhile, the difficulty in manufacturing the electromagnetic assembly is reduced.
