The spring leaf is in contact with one end of the telescopic mechanism through the second terminal; the telescopic mechanism comprises a guide shell body, a guide pipe, a guide sleeve, a thimble, a compression shaft head, a reset spring, a universal compression cap, a compression spring and a reset spring; the cap edge of the universal compression cap is in contact with the inner wall of the guide shell body; and the cap body thereof is positioned outside the guide shell body. In the invention, the direct contact of a pull wire of the switch with the spring leaf is replaced by the manner that the pull wire is led out of one end of the telescopic mechanism or the universal compression cap is directly turned to control the expansion of the telescopic mechanism, thereby achieving the pulling and turning purposes and solving a series of problems caused by the easy breaking of the power supply pull wire, and the like. In addition, the telescopic mechanism is perpendicular to the spring leaf, so as to ensure the on-off status of the spring leaf and the terminals; when the thimble pushes against the spring leaf or is released, thereby enabling the switch to be operated normally and stably in more complex environment.
