Embodiment Construction

[0017] refer to figure 1 , figure 2 , image 3 , Figure 4 As shown: a tact switch 1 is designed, which is provided with a base 104, a conduction piece sequentially arranged in the base 104, a shrapnel 103, a button 102 and an upper cover 101 buckled with the base. The shrapnel 103 is approximately rectangular, Its middle part is a circular plane 105, and two opposite outer edges of the circular plane 105 protrude outwards and downwards a section of skirt 103 that makes the shrapnel arched and symmetrical; the outer edge of the skirt 103 is arc-shaped structure; it can also be formed by cutting the outer circle of diameter B; the symmetrical sides on both sides of the skirt 103 are tangent to the outer circle of the circular plane 105 to form two parallel straight sides, which can also be larger than the circular plane 105 diameter, formed as image 3 Skirt width A shown.

[0018] In the above tact switch, the circular plane 105 is integrally formed with the symmetrica...

Abstract

The invention discloses a touch switch and a manufacturing method thereof. The touch switch comprises a base, a switching-on plate, a spring plate and a key, the three of which are orderly arranged in the base, and an upper cover locked with the base; the spring plate is appropriately rectangular, the middle part of the spring plate is a circular plane, and skirts which are capable of enabling the spring plate to be arched and symmetrical extend outwards and downwards from the two opposite outer edges of the circular plane; the outer edges of the skirts are of cambered structures; the symmetrical edges on the two sides of each skirt are tangent with the outer circle of the circular plane to form two parallel straight edge. The spring plate of the touch switch is of an appropriately strip-like skirt arched structure, and compared with a square spring plate, the travel of pressing can be reduced and the pressing feel is more comfortable; the spring plate of the touch switch is long in service life.

Description

technical field [0001] The invention relates to a light touch switch; in particular, it relates to a production method of a light touch switch and a switch shrapnel. Background technique [0002] In the prior art, there is a light touch switch, which is composed of a base, shrapnel arranged in the base in sequence, a button and an upper cover that is fastened to the base. The shrapnel has a square structure; the square shrapnel structure has the following defects: stamping The production process is complicated, the stroke is long when pressed, and the edges of the entire square shrapnel are in contact with the base. The consistency of the hand feeling is not good, the contact is unstable, and the life of the shrapnel is short. Contents of the invention [0003] The object of the present invention is to provide a tact switch with a long service life and a good pressing feel in view of the above-mentioned defects of the prior art. [0004] A tact switch is provided, inclu...
