[0033] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. The same symbols are used for the same configurations as those described in the background art, and detailed descriptions are omitted.

[0034] Fig. 1 is a sectional view of a movable contact body according to a first embodiment of the present invention. On the adhesive layer 2 under the flexible insulating film 1, a plurality of dome-shaped movable contacts 3 made of conductive metal sheets are bonded to form a plurality of movable contact bodies 30.

[0035] As an example, a case where these movable contact bodies are used as movable contact bodies for mobile phones will be described below. Fig. 2 is an exploded perspective view of a movable contact body for a mobile phone. The movable contact body having the movable contact point 3 in the center of the cross array 15 (the central movable contact body in FIG. 1 ) is used for determining operation. In this fixe...

[0044] Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. Parts having the same structure as those described in the background art or the previous embodiment are assigned the same symbols, and detailed description thereof will be omitted.

[0045]Fig. 4 is a sectional view of a movable contact body according to a second embodiment of the present invention. On the adhesive layer 2 under the flexible insulating film 1, a plurality of dome-shaped movable contacts 3 made of conductive metal sheets are bonded to form a plurality of movable contact bodies.

[0046] As described in the first embodiment, it is necessary to increase the reverse force of the movable contact body (the central movable contact body) for determining the operation, and thus, as shown in FIG. 14 Bond the movable contact 16 under the movable contact 3 in a state concentric with the movable contact 3 . The movable contact 16 is the same as the movable c...

Abstract

The invention relates to a movable contact body, comprising a movable contact maintaining to be on a sticking layer under an insulating film and a movable contact coinciding on the insulating film. The movable contact body has the advantages of large opposite acting force and good durability.

Description

technical field [0001] The present invention relates to a movable contact body used in switches for operation panels of various electronic devices. Background technique [0002] A movable contact body formed by bonding a dome-shaped movable contact to a flexible insulating film is widely used in switches for operation panels of electronic equipment. [0003] Fig. 14 is a sectional view of a conventional movable contact body. In the figure, the dimension in the thickness direction is exaggerated for ease of understanding. On the adhesive layer 2 under the flexible insulating film 1, a plurality of dome-shaped movable contacts 3 made of conductive metal sheets are bonded to form a plurality of movable contact bodies 30. [0004] A plurality of movable contact bodies are arranged in each switch for an operation panel. FIG. 15 shows an exploded perspective view of a movable contact body for a mobile phone as an example. As shown in the figure, a plurality of movable contacts...
