[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4In the embodiment of the utility model, the three-speed rocker switch includes a base 2 and a cover 1 installed above the base 2. The cover 1 has bosses integrally formed on both sides and inserted into the holes on both sides of the inner hole of the base 2. The cover 1 and the base 2 are movably connected through the bosses. A spring 3 is fixedly connected to the middle of the bottom end of the cover 1. A fulcrum terminal 9 is provided in the middle of the lower part of the base 2. A silver point terminal 8 is provided on one side of the fulcrum terminal 9 below the base 2. A two-way silver point terminal 10 is provided on the other side of the fulcrum terminal 9 below the base 2. A rotor 4 is slidingly provided at the bottom end of the cover 1. A spring 3 is clamped between the rotor 4 and the cover 1. A contact piece 5 is provided above the fulcrum terminal 9 below the rotor 4. A spring terminal 11 is fixedly connected above the two-way silver point terminal 10. Static contacts 7 are fixedly connected above the silver point terminal 8, the spring terminal 11 and the two-way silver point terminal 10. The two ends of the contact piece 5 are fixedly connected to moving contacts 6 corresponding to the static contact 7.
