Embodiment Construction

[0025] Hereinafter, the best mode for implementing the switchgear of the present invention will be described with reference to the drawings.

[0026] [Structure of the first embodiment of the present invention]

[0027] figure 1 It is a figure which shows the 1st Embodiment of the switch device of this invention, (a) figure is a side sectional view which shows the initial state when a key top is not pressed, (b) figure is a side sectional view which shows a key top when it is pressed. .

[0028] Such as figure 1 (a) As shown in the figure, the first embodiment of the present invention includes: a central fixed contact 3; a peripheral fixed contact 4; In the receiving portion 1a surrounded by the outer wall of the bracket 1 and formed lower than the outer wall, two metal dome-shaped movable contacts 7 are overlapped and accommodated. Selectively conducting with the central fixed contact 3. The movable contact 7 is formed by bulging a metal plate to one side to form a bulgi...

Abstract

The present invention provides a switch apparatus, which can reduce moment acting on soft braze welding part for installing surface soft braze welding outer connecting terminal. The apparatus includes: a bracket (1), which is arranged with central permanent joint (3) and circumjacent permanent joint (4), outer connecting terminals (5, 6) connecting with each permanent joints (3, 4) on a installation surface (1c); a movable contact (7), which is onstates with central permanent joint selectively; a cover (2), which is arranged with inclined piece (2a); an operating component (10), which is arranged with pressing part (10a), elastic part (10b) and action part (10c), frame part (10d); a limitator (1b), setting on the bracket for restricting the remotion of the pressing part of the operating component which applies pressure through a keyboard top (9), and the height position of the contact part that is soffit part (10a2) of the pressing part of the operating component contacting with the limitator is lower than that of the central permanent joint.

Description

technical field [0001] The present invention relates to a switchgear having an operating member that is pressed and operated laterally along a mounting surface. Background technique [0002] Patent Document 1 discloses such a conventional technology. This prior art includes: central fixed contacts that are arranged in the center; peripheral fixed contacts that are arranged in the periphery; a case in which these fixed contacts are arranged; A metal dome-shaped movable contact whose contact is always conducting and selectively conducts with the central fixed contact. The central fixed contact and the peripheral fixed contacts are respectively connected to external connection terminals held by the bracket. In addition, a cover body is provided which covers the bracket and has an inclined piece arranged to face the movable contact. [0003] In addition, an operating member is provided, and the operating member includes: a pressing part, which is applied with a pressing force...
