The tension of the tension spring 5 causes the rear end of the spring 4 to press tightly against the supporting piece 201, and the same side of the supporting piece 201 and the positioning piece 202 is connected by a vertically arranged connecting piece. 203 are interconnected, a first through hole 204 is provided on the connecting piece 203, and a second through hole 205 is provided on the supporting piece 201 and the positioning piece 202. The supporting piece 201, the positioning piece 202 and the connecting piece 203 are all embedded in the base 1, and the lower end of the positioning piece 202 extends through the base 1 to the bottom of the base 1, and the upper end of the positioning piece 202 and the upper end of the supporting piece 201 extend upward outside the base 1. A slot 6 is provided in the base 1 to cooperate with the connecting piece 203 and the supporting piece 201, and the lower ends of the connecting piece 203 and the supporting piece 201 abut against the bottom surface of the slot 6, and the static terminal 3 is arranged below the spring piece 4.

[0017] The utility model embeds the support piece 201 and the positioning piece 202 in the base 1 together, so that the movable terminal 2 and the base 1 form a multi-point support connection structure, which effectively improves the stability of the movable terminal 2, eliminates the technical problem of tilting and deformation of the movable terminal 2 when subjected to force, ensures the stability of the finished switch stroke, and improves the user experience.

[0018] The movable terminal 2 and the static terminal 3 are both embedded in the base 1 by insert injection molding, and the first through hole 204 and the second through hole 205 are both filled with the base 1, thereby further improving the connection tightness and working stability between the movable terminal 2 and the base 1.
