Problems solved by technology

[0004] The above-mentioned implementation mode brings convenience to the user, but at the same time, there are also factors that hinder the development of the button switch to be thinner and smaller. Due to the addition of a light-transmitting layer that can evenly spread the light of the LED lamp, the overall height of the button switch The relative increase makes it go against the current trend of miniaturization of button switches, and because of the increase in height, the user's operating comfort will also decrease, which will become obstacles to the improvement of button switches

Embodiment Construction

[0016] Below, the present invention will be further described in detail with reference to the accompanying drawings.

[0017] see Figure 1 to Figure 4 , a preferred embodiment of the button switch of the invention mainly includes a pressing layer 1 and a reversal plate 2 integrally placed under the pressing layer 1 .

[0018] The pressing layer 1 is roughly in the shape of a rectangular plane and includes a plate-shaped pressing area 10. The pressing area 10 is provided with an upper surface 101 and a lower surface 102. An extension 103 is provided on the surface 102, and the extension 103 is parallel to a printed circuit board (not shown) to maintain the stability of the pressing layer 1 on the printed circuit board. The pressing area 10 , the extension portion 103 and the printed circuit board (not shown) together form a storage space 100 , which can accommodate the reversal sheet 2 in contact with the printed circuit board. Two notches 105 are oppositely formed on opposi...

Abstract

The invention relates to a button switch mainly comprising a press layer and at least one reversal film, wherein the press layer is provided with an upper surface and a lower surface, and the edge of the press layer is provided with an extending part protruding out of the lower surface. The press layer has favorable light transmission and elasticity and can uniformly scatter light rays emitted bya light source to the upper surface of the press layer through refraction.

Description

【Technical field】 [0001] The invention relates to a button switch which can be used as an operation switch in various electrical equipment, in particular to a dome-shaped movable contact point assembly with reversing function. 【Background technique】 [0002] As the structure of the existing contact plate and the push button switch using the contact plate, the base with the fixed contact, the dome-shaped reversal piece with the fixed contact on the base, and the sticking on the reversal piece can freely Composed of bent adhesive sheets. The above-mentioned pasting sheet is pasted on the outside of the reversal film. Usually, the pasting sheet is pressed from the decorative panel or the pressing area plate of the electronic equipment, so that the reversal film bonded to it is reversed and comes into contact with the fixed contact, thereby performing For the switching of contacts, on the electronic equipment where the button switch is applied, there is usually a plastic button...
