Embodiment Construction

[0015] The present invention will be further elaborated below with reference to the accompanying drawings.

[0016] Please refer to the attached figure 1 to attach image 3 , in this embodiment, this kind of miniature silent tact switch includes: a hollow housing 1, one end of the housing 1 is provided with a switch cap 10, and the switch cap 10 is connected to a central axis 6, so The central axis 6 is installed on the switch circuit board 5, and a switch contact piece 8 is sleeved on the central axis 6, and a first elastic member 9 is arranged between the switch contact piece 8 and the switch cap 10. The other end of the central shaft 6 is connected to the second elastic member 4 . Wherein, the switch circuit board 5 is provided with a conductive contact piece 7 corresponding to the switch contact piece 8. When the switch cap 10 is pressed down by force, the first elastic member 9 pushes the switch contact piece 8 to move down to contact with the conductive contact piece. ...

Abstract

The invention discloses a micro silent touch switch. The micro silent touch switch comprises a hollow shell; a switch cap is arranged at one end of the shell; the switch cap is connected to a middle shaft; the middle shaft is arranged in a switch circuit board in a penetration manner; the middle shaft is also sleeved with a switch contact piece; a first elastic part is arranged between the switch contact piece and the switch cap; the other end part of the middle shaft is connected to a second elastic part, wherein a conductive contact piece corresponding to the switch contact piece is arranged on the switch circuit board; when the switch cap presses downwardly due to stress, the first elastic part pushes the switch contact piece to move downwards to be in contact with the conductive contact piece to turn on the switch, and to compress the second elastic part at the same time; and when external force is removed, the second elastic part recovers elasticity deformation to reset the switch contact piece to disconnect the switch. By virtue of the micro silent touch switch, through matching of two springs and the middle shaft, the switch movement journey is prolonged; and meanwhile, the switch operating sound is eliminated, the switch can be longer in service life, and the self structure of the switch is relatively simple.

Description

technical field [0001] The invention relates to the technical field of switch structures, in particular to a miniature silent tact switch with low operating sound, long stroke and long service life. Background technique [0002] There are roughly two types of existing tact switches. One is dome tact switches, which have the advantages of simple structure and low cost, and the disadvantages of loud sound when pressed and deformed, and are prone to permanent deformation and failure. The other is the silicone tact switch. The advantage is that the sound is low when pressed, but the disadvantage is that the silicone is easy to age and cause the switch to fail. However, these two types of tact switches have a short stroke and a limited switch life. Contents of the invention [0003] The purpose of the present invention is to provide a miniature silent tact switch, which solves the existing technical problems of loud operating sound, long stroke and short life. [0004] In ord...
