Description of the invention (]) The present invention relates to the structure of push button switches which are used by operation switches of various electronic devices, especially the structure of fixed terminals and movable contacts provided in the housing. The conventional push button switch structure used as an operating switch is generally known to have a fixed contact made of conductive metal fixedly exposed on the inner bottom surface of a box-shaped case formed of an insulating material such as synthetic resin, and the opposite The fixed contact is arranged on the dome-shaped movable contact which is also made of metal, and the dome-shaped top of the movable contact is pressed by the protrusion provided on the sliding free tube seat in the housing receiving part, to promote A structure in which the dome-shaped movable contact is inverted and separated from the fixed contact. In addition, it is generally known that the movable contact is formed in a flat shape, and the center of the flat movable contact is cut and erected to form a contact piece, and with the reversal of the rubber spring provided in the housing receiving portion, Acting, the rubber spring presses the above-mentioned contact piece, and the fixed contact structure of the contact piece is contacted or separated. It is also known that in this case, a structure in which a carbon-based contact is bonded to the bottom end of the rubber spring as a movable contact instead of the movable contact. In the aforementioned conventional structure, since the reversing action of the dome-shaped movable contact is used to switch the switch contact, it is suitable for operating a button switch with a short stroke. In contrast, the conventional structure described later is due to the reversing action of a rubber spring It is used to switch the switch contact, so it is more suitable for operating a button switch with a long stroke. However, in the above-mentioned conventional button switch structure, in order to obtain a long operation stroke, the button switch needs to have a longer quotient from the rubber spring seat surface to the top, and it is necessary to set the rubber spring height to be longer. The problem of increasing the outer dimension of the button switch in the height direction.

The stem 5 is formed into a substantially rectangular shape from a molding material such as a synthetic resin, and a flat operation part 5 a that can be operated by a finger or the like is provided on the upper surface. The bottom surface side corresponding to the operation portion 5a is formed with a pressing surface portion 5b that abuts the upper surface of the operating portion 4b of the rubber spring 4 and urges the rubber spring 4 to bend toward the movable contact 3 side. Furthermore, a flange portion 5c is formed on the periphery of the socket 5, and when the socket 5 moves and returns, the flange portion abuts a cover 6 described later to restrict the socket 5 from jumping out of the housing 1. The cover 6 is formed in a rectangular shape by a flat metal plate, and a center 6 a is provided at the center of the cover 6 through which the operation part 5 a of the socket 5 can be inserted. By providing the cover 6 to the opening of the casing 1, the movable contact 3, the rubber spring 4, and the socket 5 can be prevented from jumping out. In the above embodiment, when the tube holder 5 is pressed, the rubber spring 4 is pressed by the tube holder 5, and the skirt portion 4a is buckled and reversed, so that the actuating protrusion 4c passes the above of the movable contact 3.

In addition, the contact piece 3e is disposed at the position of the housing 1, and is bent downward from the inner bottom surface of the receiving portion 1a and formed in the lower portion of the concave portion 1b, so that it is not necessary to increase the height of the rubber spring 4. It is also possible to increase the stroke of the above-mentioned actuating protrusion 4 c to the extent of the above-mentioned recess 1 b, so it is not necessary to increase the height dimension of the button switch to provide a button switch structure with a longer operation stroke. In addition, the movable contact 3 is formed by an elastic metal plate, which can reduce the contact resistance compared with the structure of bonding a carbon contact to the bottom surface of a rubber spring. Therefore, it is not necessary to use a precious metal such as gold for the fixed contact 2b. Facilitates low cost. FIG. 6 is a cross-sectional view of a push switch according to another embodiment of the present invention. In the above-mentioned embodiment, although the turning portion 3 d of the movable contact 3 is configured to be bent downward and arranged to be in contact with the inner bottom surface of the recessed portion 1 b of the housing 1, the embodiment shown in FIG. The bottom bending dimension of 3 d is set to be a few distances from the inner bottom surface of the concave portion 1 b of the housing 1 at this time. At this time, if the size of the above bending portion 3 d may be somewhat uneven during bending processing, The bent portion 3 d 尙 can abut against the inner bottom surface of the recessed portion 1 b of the housing 1, and can prevent the movable contact 3 from floating from the installation surface of the housing 1.

The connecting part can be formed by shaking the contact piece with respect to the bone part, and a bending part for bending the contact piece downward is formed at the connecting part, so a movable contact having a simple shape and stable contact can be obtained. At the same time, it is formed by an elastic metal plate, and an arc-shaped through-hole is opened in the central part of the bone part, and a contact piece is formed in the center of the through-hole, which is proportional to the bottom surface of the rubber spring. The structure of the quality contact can reduce the contact resistance, and the fixed contact does not need to use precious metals such as gold to promote low cost. In addition, a rubber spring is arranged on the bone part and the operating protrusion is opened through the center of the bone part. The through-hole pushes the contact piece, so that the stroke of the actuating protrusion of the rubber spring can be increased with a simple structure. Also, those who dispose the turning portion of the contact piece from the inner bottom surface of the recessed portion may not be used in the bending process of the turning portion. Variations in size occur, and because the turning portion can abut the inner bottom surface of the recessed portion of the housing, the movable contact is prevented from floating from the installation surface of the housing.
