Problems solved by technology

[0005] However, in the method of applying (injecting) resin to the inside of the switch case, it is difficult to fill the inside of the switch case without gaps, and there is a possibility that a gap may be generated between the resin and the inside of the switch case.
Then, when water drops adhere to the lower part of the switch case, the water drops intrude into the main body of the switch, and there is a danger of reducing the waterproof performance of the push button switch.
[0006] In addition, the coating operation of thermosetting resin requires a lot of time and skill, which will greatly reduce productivity.

Abstract

The invention provides a push switch, which can improve water-proof performance of a push switch and production efficiency. The push switch comprises: a button (10) made of a flexible material having a cap shaped top operation part (11), a flat part (14) formed extending laterally from an edge of an opening in the top operation part (11), and a side wall (15) formed extending downward from an outer edge of the flat part; a switch substrate (20) fitted in close contact with the inner circumference of the side wall and abutting the bottom face (14B) of the flat part (14) of the button (10); and a switch arranged inside the button, on the switch substrate, wherein the outer circumferential face of the side wall (15) of the button (10) and the bottom face (20A) of the switch substrate are covered by integrally molded resin.

Description

technical field [0001] The invention relates to a push button switch. Background technique [0002] As a conventional push button switch, there is, for example, a switch operation device used in a vehicle for pressing from the outside (Patent Document 1). The button switches as Figure 10 (a), Figure 10 As shown in (b), it has the switch case 101 made of hard resin, the switch button part 102 made of soft resin, and the switch main body part 107. [0003] The switch case 101 is formed as a rectangular parallelepiped box having a space inside for accommodating the switch button portion 102 . The switch main body 107 is mounted on the inside of the switch button 102 , and a thermosetting resin 111 is applied on the inside of the switch case 101 . Through the thermosetting resin 111 , the switch main body 107 can be firmly fixed on the switch case 101 or the switch button 102 , and can be used as a waterproof protection for the switch main body 107 . [0004] Patent Documen...
