Abstract
The utility model discloses an improved structure of a wall trip switch, which comprises a base, a circuit board, a draw bar, a switch button, static pieces, movable pieces, a supporting plate, a trip plate and an electromagnetic mechanism. The draw bar is pressed down and a draw bar spring is compressed by a reset button, and the draw bar is positioned via a square hole of the circuit board and then fixed on the circuit board together with corners of the base. The iron-core spring is compressed when the draw bar is pressed downwards, and after the draw bar which is pressed to the bottommost position is released from the fingers, the draw bar is hooked upwards and pushes the trip plate under action of the drawbar spring to drive the trip plate and the supporting plate to move upwards together, drives the two contact pieces and leads movable contacts thereon to contact with static contacts, thereby realizing a reset state. When the switch button is pressed, an inclined on one side of the switch button contacts with one edge of the trip plate and prevents a barb of the draw bar from hooking the trip plate after pushing the trip plate to retract, thereby realizing tripping action. The improved structure can realize resetting and tripping actions by aid of the trip mechanism, and has the advantages of reasonable structure, safety and reliability and the like.
