Detailed Description

The embodiments of the invention are described in detail below, but the invention can be implemented in many different ways, which are defined and covered by the claims.

As an aspect of the present invention, there is provided a power switch, mainly used for switching on and switching off a circuit in an electric appliance circuit, comprising: the button comprises a button 1, a shell 2, a bottom plate 3, a spring 4, a movable copper sheet 5, a metal support 6, a fixed copper sheet 7 and a magnet 8 arranged in the bottom plate 3, wherein the shell 2 is connected with the bottom plate 3, a mounting cavity is enclosed between the shell 2 and the bottom plate 3, the button 1 is pivotally mounted at the top of the shell 2, the metal support 6 and the fixed copper sheet 7 are mounted on the bottom plate 3, the movable copper sheet 5 is arranged in the mounting cavity and is rotationally lapped on the metal support 6, a movable contact 9 is arranged at one end of the movable copper sheet 5, a fixed contact 10 matched with the movable contact 9 is arranged at one end of the fixed copper sheet 7, the upper end of the spring 4 is connected with the button 1, and the lower end of the spring 4 is connected with the movable copper sheet 5.

Preferably, a spring connection post 11 for mounting the spring 4 is protrudingly formed on the upper surface of the movable copper sheet 5. Preferably, the lower surface of the button 1 is formed with a recess 12 for mounting the spring 4.

The utility model discloses in, metal support 6, fixed copper sheet 7 together bury in bottom plate 3, set up magnetite 8 in bottom plate 3, and movable copper sheet 5's bottom is taken on metal support 6, and the fulcrum of movable copper sheet 5 wane motion is regarded as to the overlap joint point. The bottom of the spring 4 is sleeved on a spring connecting column 11 at the upper end of the movable copper sheet 5, and the other end of the spring 4 extends into a concave part 12 at the bottom of the button 1. The button 1 is pushed to enable the spring 4 to swing back and forth left and right, the center of gravity of the spring 4 is deviated left and right due to compression, the spring 4 applies force to the movable copper sheet 5, the center of gravity of the movable copper sheet also deviates left and right, and therefore the movable copper sheet 5 makes seesaw motion on the metal support 6. When the tip of the rocker falls down, the rocker contacts the fixed copper sheet 7, and when the rocker lifts up, the fixed copper sheet 7 is disconnected.

Since the technical scheme is used, the utility model discloses increased magnetite 8 in the below of movable copper sheet 5 and the contact of fixed copper sheet 7, utilized the hall effect principle, when electron reachd another contact from a contact under the strong magnetic field effect, the electron is the dispersed state and passes through narrow passage between the contact, concentrates through the electric arc that narrow passage produced between the contact less than original electron to reduce, weaken the condition that electric arc melting contact material made, with the life performance who improves the switch. The movable copper sheet 5 and the fixed copper sheet 7 reduce the loss of the movable contact 9 and the fixed contact 10 in the contact process, and the purpose of prolonging the service life of the switch is achieved from the surface.

The utility model discloses a built-in magnetite 8 passes through the electric current influence back to the contact site, makes the contact reach reinforcing arc extinguishing ability, increases and to cross the electric quantity to reach the life-span ability that promotes the switch.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
