Problems solved by technology

The through hole in the middle of the cover plate is mainly used for guiding the button. Since the button needs to move smoothly, there is an obvious gap between the through hole in the middle of the cover plate and the button, so that the switch function component does not have a sealed cavity, resulting in the product being incompatible with the product during use. Contact with water vapor or fine dust in the air may fail at any time, and cannot achieve waterproof and dustproof effects, so the service life and safety of the product cannot be effectively guaranteed

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings:

[0021] Refer to the attached Figure 1-3 : A waterproof tact switch in this embodiment includes a clip terminal 1, a base 2, a spring sheet 3, a second dustproof membrane 4, a waterproof rubber pad 5, a first dustproof membrane 6, The button 7 and the cover plate 8, the base 2 is recessed from the upper end surface to form a accommodating cavity 21, and the four corners of the upper end surface of the base 2 are extended upward from the upper end of the accommodating cavity 21 with isolation flanges 22. A guide post 23 extends upward from the upper end surface of the base 2; there are two clip terminals 1 in total, and the upper end of one clip terminal 1 is located at the middle contact 11 in the accommodating cavity 21, The upper end of the other clip terminal 1 forms two side contacts 12 on both sides of the middle contact 11, and the lower ends of the two clip ter...

Abstract

The invention discloses a waterproof light touch switch. The base is recessed downward from the upper end surface to form an accommodating cavity, and the four corners of the upper end surface of the base are provided with isolation flanges extending upward from the upper end of the accommodating cavity, and the upper end surface of the base also extends upward with guides. There are two clamp terminals, the lower ends of the two clamp terminals protrude out of the base to form pins, and the structures of the two pins are left-right symmetrical. The waterproof tact switch designed by the present invention is provided with a first dustproof membrane and a second dustproof membrane respectively on the upper and lower sides of the waterproof rubber pad to form a composite structure, and the first dustproof membrane can prevent external dust from entering the button and the waterproof rubber pad. between, and buffer the bottom of the button to reduce the damage to the waterproof rubber pad and improve the life of the tact switch.

Description

technical field [0001] The invention relates to a tact switch, in particular to a waterproof tact switch. Background technique [0002] Tact switches have the advantages of small contact resistance load, accurate operating force error, and diversified specifications, and are widely used in electronic equipment and white goods. The tact switch of the traditional structure is mainly composed of a base, a button and a cover plate. The cover plate has a through hole, and the button cooperates with the through hole. The through hole in the middle of the cover plate is mainly used to guide the button. Since the button needs to move smoothly, there is a clear gap between the through hole in the middle of the cover plate and the button, so that the switch function component does not have a closed cavity, resulting in the product being in use. Contact with water vapor or fine dust in the air may fail at any time, and it cannot achieve the effect of waterproof and dustproof, so the s...
