Embodiment 2

[0032] Figure 5 It is the expression structure of the extended shrapnel of the left shrapnel 7 and the right shrapnel 8, and other structures are not limited thereto.

[0033] The working process of this example: this structure is through the setting of the left elastic piece 7 and the right elastic piece 8, the elastic force of the elastic piece is doubled, so that the contact surface of the elastic piece and the energized foot is completely and fully contacted, so as to achieve a better energized state during the energization process.

[0034] First, through the bending point 15 of the left shrapnel 7 and the right shrapnel 8 (hereinafter, the left shrapnel and the right shrapnel are collectively referred to as shrapnel), the shrapnel is bent to an effective curvature to ensure the shrapnel and the contact point 16 of the energized foot. The contact at this position; at the same time, after assembly, the shrapnel and the plastic contact point 17 of the push shaft are design...

Abstract

The invention provides a key switch. The key switch comprises a cover plate, a push shaft, a base and elastic sheets, wherein the cover plate is arranged on the base; the push shaft penetrates the cover plate and is arranged in the base; a spring is arranged between the push shaft and the base; two left elastic sheets and two right elastic sheets are symmetrically arranged on two sides outside thelower end of the push shaft; four power-on pins are arranged in the base; the two power-on pins are arranged corresponding to the two left elastic sheets; the other two power-on pins are arranged corresponding to the two right elastic sheets; and the push shaft comprises a push shaft body and a connecting block. The key switch has the advantages that: through the double elasticity of the elasticsheets, the contact surfaces of the elastic sheets and the power-on pins are in full contact, so that the effect of more excellent power-on state in the power-on process is achieved; after a product is processed in a furnace, if the plastic is slightly reduced and deformed, and the full contact of the contact surfaces of the elastic sheets and the power-on fins can be ensured.

Description

technical field [0001] The invention belongs to the technical field of electric switch production, and in particular relates to a key switch. Background technique [0002] Such as figure 1 As shown, the key switches in the current market are all designed with independent bubble point contact or sliding plate spring, the contact is easy to deform, and the plastic or shrapnel shrinks after welding, resulting in flickering or no power-on phenomenon; power-on The distance between the pin and the energized pin 5 is likely to be too close, and there is a hidden danger of non-insulation in a high-temperature and high-humidity environment; the shrapnel 4 is in single-point contact with the contact surface of the energized pin, and the shrapnel is easily deformed at the same time, resulting in insufficient contact. Contents of the invention [0003] The purpose of the present invention is to provide a key switch, which can solve the problem that the key switch in the market cannot...
