Abstract

The invention discloses a high-life mute micro-switch, which comprises a base, a cover covering the base, an elastic body and a flexible body, wherein the cover covers the base to form an accommodating cavity; a guide core is arranged in the accommodating cavity; an upper opening through which the upper end of the guide core passes is formed in the cover; the elastic body is arranged in the accommodating cavity and is located at the lower part of the guide core; the flexible body is arranged on the lower end surface of the cover and is located at the upper part of one end of the elastic body;a plurality of upper elastic strips are arranged at one end of the elastic body in a manner of extending upwards; the plurality of upper elastic strips are located below the flexible body; and when pressing on the guide core is released, the elastic body rebounds due to deformation recovery, and the upper elastic strips are prompted to touch the flexible body and flexibly deform, so that the impact force is reduced through generated buffer force to achieve the muting effect. The micro-switch disclosed by the invention has the muting function, a good muting effect is achieved, and meanwhile, the whole life is prolonged and reaches 80,000,000 times.

Description

technical field

[0001] The invention relates to a micro switch, in particular to a high-life silent micro switch. Background technique

[0002] Micro switch is a commonly used switch mechanism. It is a contact mechanism with a small contact interval and a quick action mechanism that performs switching actions with a specified stroke and a specified force. It is widely used in industry, electronics, machinery, and governance. Gold, electricity and other fields.

[0003] The working principle of the existing micro switch is: the external mechanical force acts on the action reed through the transmission element (press pin, button, lever, roller, etc.), and when the action reed moves to the critical point, an instantaneous action is generated to make the action The moving contact at the end of the reed is quickly connected or disconnected from the static contact.

[0004] The existing micro switch usually adopts the method of setting the movable contact on the action reed. Bef...

Embodiment Construction

[0033] In order to further illustrate the technical means and functions adopted by the present invention to achieve the intended purpose, the specific implementation modes of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0034] Please refer to Figure 1 to Figure 6 , the embodiment of the present invention provides a high-life mute micro switch, which includes a base 1 and a cover 2 that is closed on the base 1, and the cover 2 is closed on the base 1 to form an accommodating cavity. A guide core 3 is arranged in the accommodating cavity, and an upper opening 21 is opened on the cover 2 for the upper end of the guide core 3 to pass through. The micro switch of this embodiment also includes an elastic body 4 disposed in the accommodating cavity and below the guide core 3, and a flexible body 5 disposed on the lower end surface of the cover 2 and positioned above one end of the elastic body 4, w...
