Slide switch

This creation is related to slide switches, especially for slide switches that require thin electrical devices.

Such a slide switch is known as a "slim slide switch" as disclosed in Japanese Patent Publication No. M407479 (Application No. 100200237), as shown in Figs. 1 and 2. The thin slide switch 200 includes a base 210 and a topless box-shaped insulator. The front side wall is provided with an opening 211. An upper cover 220 covers the base 210 and has a tilt at the center of the rear end. a recess 221; an operating body 230 is formed by an operating handle 231 and a sliding portion 232. The sliding portion 232 is disposed in a hollow portion of the base 210. The operating handle 231 is extended by the opening 211 of the base 210. The bottom of the base 210 is slidable along the opening 211, and a swaying protrusion 233 is formed at the center of the rear end of the sliding portion 232, and a swaying mechanism is formed with the swaying recess 221; and a contact piece 240 The device is mounted on the bottom surface of the sliding portion 232 and moves with the movement of the operating body 230.

The thin slide switch has a contact piece which is mounted on the bottom surface of the sliding portion and moves with the movement of the operating body. Each time it slides, a friction is generated, and finally the switch base and the contact piece are worn, which seriously affects the electronic device. The life of the device.

The present invention provides a slide switch in which the contact piece is changed to a fixed type without sliding, which reduces wear and improves the life of the electronic device, and includes: a base, which is a topless box-shaped insulator, The hollow portion is an accommodating space, and the front wall is provided with an opening, the bottom surface of which is provided with a central fixed contact and two left and right fixed contacts, and a fixed protrusion is disposed on the central fixed contact, the fixing protrusion is formed by the bottom surface Extending through the central fixed contact; an upper cover covering the base, the top surface of which is a main piece, and a center of the rear end of the main piece is provided with a tilting recess; an operating body is provided by an operating handle and a sliding portion is disposed in the accommodating space of the base, and each of the left and right sides of the sliding portion is respectively provided with a pressing protrusion, and the operating handle protrudes from the opening of the base by the opening of the base, and The left and right sliding portions of the sliding portion can be formed, and the rear end of the sliding portion forms a swaying mechanism with the swaying concave portion; and a contact piece is formed by a flat central portion and left and right wing portions which are slightly upwardly tilted The central portion is provided with a fixing hole for fixing a protrusion protruding from the central fixed contact to fix the contact piece, and the central portion is constantly abutted against the central fixed contact, and the left and right wings are Each of the tail ends is provided with a movable contact.

The function of the creative slide switch: the contact piece is fixed at the center of the base At the contact point, under the normal state, the contact piece is tilted to the left and right by two movable contacts, wherein the right movable contact is pressed by the right pressing protrusion of the sliding portion of the operating body, so that the contact piece is movable to the right The contact abuts against the right fixed contact and electrically connects the right side of the slide switch; secondly, if the sliding portion of the operating body slides to the left, the right movable contact is tilted upward and leaves the right The fixed contact is electrically non-conductive, and the left pressing protrusion of the sliding portion presses the left movable contact to abut the left movable contact and electrically connect the left side of the sliding switch.
