A common foot 3 is centrally arranged inside the base 1, and a first spring 4 is arranged on the common foot 3. The other end of the first spring 4 contacts with a contact piece 17. The contact piece 17 is provided with three contacts 5, which are suitable for achieving three-speed conduction and improving practicality. A rotor 6 is arranged on the contact piece 17, and a groove is centrally arranged on the surface of the rotor 6. A second spring 7 is arranged in the groove, and the other end of the second spring 7 contacts with a button 8. A rubber cover 9 is arranged on the surface of the base 1, and a self-locking mechanism 2 is arranged in the rubber cover 9. A groove is arranged at the bottom of the rubber cover 9, and a terminal 10 is arranged on the surface of the base 1.
