Embodiment approach

[0034] figure 1 is a cross-sectional view of a push switch according to an embodiment of the present invention, figure 2 It is an exploded perspective view of the push switch. image 3 is a plan view of the operating body of the push switch, Figure 4 yes image 3 Cutaway view of line 4-4. also, Figure 5 is a cross-sectional view showing the operating state of the push switch, Figure 6 It is an external view of the operation body of another embodiment.

[0035] Such as figure 1 as well as figure 2 As shown, the push switch according to this embodiment has a switch case 11 made of a square insulating resin having a substantially circular recess 11B partially recessed from the bottom surface of an upper opening 11A. Furthermore, on the inner bottom surface of the recessed portion 11B, the central fixed contact 2 and a pair of outer fixed contacts 3 at an equal distance across the central fixed contact 2 are exposed. In addition, terminals 4 and 5 respectively conn...

Abstract

The invention provides a push switch. The operating body is formed of a metal plate, and a polyimide-based resin layer is provided on the upper surface. The operating body has an operating portion protruding forward and outward from the switch case at one end, and an arm-shaped driving portion at the other end. And the frame-shaped slide guide that surrounds the drive unit, the arm-shaped drive unit is compressed and pressurized to make the plate thickness thinner, and the hemispherical upper surface that contacts the lower surface of the upper cover protrudes from the slide guide The sliding contact protrusion, and the lower sliding contact protrusion which is long in the front-rear direction and abuts on the lower protective sheet.

Description

technical field [0001] The present invention relates to a push switch that can be operated from a horizontal direction parallel to the wiring board surface of the electronic equipment, which is used in input operation parts of various electronic equipment. Background technique [0002] Various electronic devices have been required to be smaller and thinner as the multi-functionality progresses, represented by mobile phones. Moreover, push switches with a sensitive sense of moderation (feeling of knots) are often used on the input operation part, and push switches are often arranged on the side of the electronic equipment to be able to operate. [0003] For the existing push switch used on the input operation part of such electronic equipment, use Figure 7 ~ Figure 10 Be explained. [0004] Figure 7 is a sectional view of a conventional push switch, Figure 8 It is an exploded perspective view of the push switch. also, Figure 9 is a cross-sectional view showing the op...
