Description

Technical Field

[0001] The utility model relates to the technical field of buttons, in particular to a low-noise and long-life button. Background Art

[0002] A button is a commonly used control electrical component, which is often used to connect or disconnect a control circuit.

[0003] The buttons on electric vehicles are generally normally closed. When the user presses the button, the circuit is connected, and when the user releases the button, the spring inside the button automatically resets the button. During the process of pressing or releasing the button, the protrusion inside the button will rub against the base inside the button to make noise. In addition, the buttons on electric vehicles are generally used outdoors, and the base inside the button needs to be protected. The existing protection and silencing method generally provides a rubber pad in the base, but the common single-layer rubber pad will undergo permanent deformation after the button is pressed multiple times, resulting in reduced silencing and protection effects, so it needs to be improved.
