Problems solved by technology

[0002] At present, the traditional seesaw switch has the following disadvantages: 1. The shape is single and dull; 2. The button takes up a lot of space, and it is inconvenient to wipe the dust on the switch button; 3. The button has a high damage rate and the service life of the button is short; 4. There is a risk of accidents caused by water immersion
The elasticity of the metal shrapnel of this type of shrapnel switch is easily weakened after long-term use, and the waterproof performance of the entire switch structure is poor, resulting in a shortened normal service life of this type of shrapnel switch

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] A shrapnel-type switch button structure, including a battery base 1, a metal shrapnel 2 arranged in the battery base 1, and a switch button 3 arranged on the battery base 1, the metal shrapnel 2 has an upwardly protruding arc Shaped spherical structure, a silicone pressing piece 4 is also provided between the switch button 3 and the metal dome 2 .

[0024] The present invention adopts a metal shrapnel with an arc-shaped spherical structure formed by one-time blanking of stainless steel, which expands to the surrounding after receiving the downward pressure, and returns to its original shape after the pressure is removed. The elastic force of the shrapnel is provided by the arc structure in the 360° direction. Therefore, its elasticity is durable and stable, and it will not deform after pressing more than 100,000 times. In addi...

Abstract

The invention discloses an elastic sheet type switch button structure, and belongs to the technical field of switch buttons. The elastic sheet type switch button structure comprises a battery core base, a metal elastic sheet arranged in the battery core base and a switch button arranged on the battery core base, wherein the metal elastic sheet is provided with an arc-shaped spherical surface structure protruding upwards, and a silica gel pressing piece is further arranged between the switch button and the metal elastic sheet. The elastic sheet is high in strength, lasting and stable in elasticity, good in waterproofness and long in service life.

Description

technical field [0001] The invention relates to the technical field of switch keys, in particular to a shrapnel type switch key structure. Background technique [0002] At present, the traditional seesaw switch has the following disadvantages: 1. The shape is single and dull; 2. The buttons take up a lot of space, and it is inconvenient to wipe the dust on the switch buttons; 3. The button damage rate is high and the service life of the buttons is short; 4. There is a risk of accidents caused by water immersion . However, the existing shrapnel switch, such as the utility model patent No. ZL201721874525.3, discloses a shrapnel type membrane switch, which includes a switch panel with an integrally formed button panel on the switch panel; Directly below, there is a pressing shrapnel in the body of the pressing shrapnel, and solid sheets are arranged on both sides; diaphragm plates are arranged on both sides of the pressing shrapnel body; an upper metal shrapnel is arranged und...
