Problems solved by technology

[0018] However, in the conventional switch device 20, since the first and second spacers 24 and 28 have the same thickness, when the operator intends to turn on the first switch part by the first operation of the operation part 21a, the second printed circuit board 25 is also pressed at the same time, so there is a problem that the second switch part is turned on
[0019] That is, there is a problem that an erroneous input occurs due to the second operation of turning on the second switch portion by the first operation of turning on only the first switch portion.

Embodiment Construction

[0039] One embodiment of the switch device of the present invention will be described below based on the drawings. figure 1 is an exploded perspective view illustrating the switchgear of the present invention, figure 2 3 and 4 are perspective views illustrating other embodiments of the second spacer according to the present invention.

[0040] if based on figure 1 , figure 2 The switchgear 1 of the present invention will be described. On the uppermost part of the switchgear 1 of the present invention, an elastic cover body 2 such as rubber is provided, and a plurality of operating parts 2a protruding upward at a predetermined height are formed on the switchgear 1 at predetermined intervals. The upper surface of the cover body 2.

[0041] A film-like, flexible upper sheet 3 is provided on the lower surface of the cover 2, and an upper electrode 3a having a size smaller than the through hole 4a of the first spacer 4 described later is formed on the upper sheet by printing...

Abstract

A switch device is provided that includes a first switch portion in which an upper electrode and lower electrodes face each other at a predetermined gap and a second switch portion having metal domes which are disposed at a lower side facing the first switch portion and expand to a predetermined height. A first spacer having a predetermined thickness A is disposed in the first switch portion to form a gap between the upper electrode and the lower electrodes, a second spacer having a thickness B equal to or greater than the expanded height of the metal domes is disposed in the second switch portion, and the thickness of the second spacer is greater than that of the first spacer.

Description

technical field [0001] The present invention relates to a switch device, and relates to a switch device capable of operating both a first switch unit and a second switch unit by pressing the same pressing position. Background technique [0002] If the conventional switch device is described based on Patent Document 1, it is as follows Figure 5 As shown, in the conventional switch device 20, a cover 21 made of a rubber plate or the like is provided at the uppermost portion, and an operation portion 21a is formed on the cover 21 . [0003] A flexible first printed substrate 22 is disposed on the lower surface of the cover 21 , and a first common electrode 23 is formed on the lower surface of the first printed substrate 22 . [0004] The first printed substrate 22 is placed on a first spacer 24 with a predetermined thickness, and a first through hole where the first common electrode 23 is located and can be bent downward is formed in the first spacer 24 24a. [0005] In addi...
