Button switch

Abstract

This invention provides a push-button switch capable of having an excellent operation feeling, while being thinned. The push-button switch comprises a housing 1 with a housing part 1a, fixed contacts 2, 3 arranged on inside bottom surface of the housing part 1a, a moving contact 4 arranged on the fixed contacts 2, 3, an operation member 6 having a press part 6d projecting from a side part of the housing 1, and an operation part 6c, and a cover body 7 mounted on upper surface of the housing 1, and having an inclined piece 7e cut and raised inside the housing part 1a. Pressing operation of the press part 6d causes the operation part 6c to slide on the inclined piece 7e to bend downwardly to press the moving contact 4. A deformation prevention part is formed to prevent the cover body 7 having the inclined piece 7e from inflating in a direction opposite to the moving contact 4 in the housing part 1a, during pressing operation of the operation member 6.

Description

technical field [0001] The present invention relates to a push button switch used as an operation switch of various electronic devices, and particularly relates to a thin horizontal push button switch. Background technique [0002] As a structure of a conventional push button switch, there is known a push button switch (refer to Japanese Utility Model Registration No. 2572590), that is, a slant piece is cut into the casing from the cover body and faces the movable contact, and is sandwiched between The operating member having an elastic operating portion between the inclined piece and the movable contact, is pressed by the pressing portion to slide the operating portion on the inclined piece and press the movable contact to switch the contact. [0003] Next, the structure of a conventional push button switch will be described with reference to the drawings. [0004] FIG. 10 is an exploded perspective view of a conventional push switch, and FIG. 11 is a cross-sectional view ...

AI Technical Summary

Problems solved by technology

[0013] However, in the structure of the conventional push button switch, since the cover body is mounted on the housing by the arm portion and the locking portion provided in the front and rear directions along the operating direction of the operating member, when the operating portion of the operating member slides on the inclined piece, At this time, the cover with the inclined piece tends to float up to the side opposite to the direction in which the movable contact is pressed, and as a result, a deviation in the amount of operation relative to the operation member is likely to occur in the reversed position of the movable contact, and the operation feeling may change. Poor, so there is a problem that hinders the thinning of the push button switch
