When the pressing handle 120 is forced to move downwards in the direction indicated by the arrow F1 in fig. 5, the first driving surface 1421 on the pressing handle 120 will abut against the elastic arm 152, as shown in fig. 7, and during the downward movement of the pressing handle 120, the first driving surface 1421 will push the elastic arm 152 to swing away from the pressing handle 120, i.e., swing in the direction indicated by the arrow F2 in fig. 7, and drive it to move downwards, thereby deforming the elastic arm 152; when the pressing handle 120 moves down continuously to make the vertex 1423 of the driving portion 142 pass over the elastic arm 152, the elastic arm 152 loses the acting force and recovers the deformation, and instantly slides down along the second driving surface 1423 under the action of its own elastic force and impacts the sidewall of the metal terminal 160, as shown in fig. 8-10, so that a strong impact sound and vibration hand feeling are generated at the moment of conduction, the conduction is synchronized with the sound-emitting and vibration hand feeling, and a strong pressing hand feeling is provided, and meanwhile, the elastic arm 152 tightly abuts against the metal terminal 160 under the action of its own elastic force to keep the signal conduction.

During the downward movement of the pressing handle 120, the pressing handle 120 compresses the restoring member 130 to deform it. When the pressing handle 120 is released, the pressing handle 120 moves upward to reset under the action of the resetting piece 130, and in the process of moving upward the pressing handle 120, the second driving surface 1423 of the driving part 142 acts on the elastic arm 152 to push the elastic arm 152 to swing in the direction away from the pressing handle 120, so that the elastic arm 152 is separated from the metal terminal 160 to disconnect the signal; when the pressing handle 120 moves up to the vertex 1423 of the driving portion 142 and passes over the elastic arm 152, the elastic arm 152 loses the acting force and recovers the deformation, thereby sliding along the first driving surface 1421 and finally abutting against the abutting portion 141, so that the elastic arm 152 and the metal terminal 160 are kept in a separated state, and the signal is kept disconnected.
