Technical Field

[0001] The utility model relates to the technical field of key switches, in particular to a key switch which is easy to disassemble. Background Art

[0002] Push button switches mainly refer to light-touch push button switches, also known as light-touch switches. Push button switches are a type of electronic switch and belong to the category of electronic components. When in use, pressure is applied in the direction of the switch operation to meet the operating force conditions to close the switch function. When the pressure is removed, the switch is disconnected.

[0003] At present, when the existing key switch is installed, the lower end thereof passes through a thin plate with a through slot, and the screws are passed through the upper end of the key switch and then screwed into the corresponding thin plate for installation. As a result, it is very cumbersome to disassemble and assemble the screws many times during subsequent maintenance, repair or replacement. If the screws are rusted, the disassembly and assembly of the key switch is even more inconvenient. Therefore, the present invention proposes a key switch that is easy to disassemble. Utility Model Content

[0004] The utility model aims to provide a key switch which is easy to disassemble, and has the advantage of being easy to disassemble. It solves the problem that when the existing key switch is installed, after the lower end thereof passes through a metal sheet with a through groove, a screw is passed through the upper end of the key switch and then screwed into the corresponding metal sheet for installation, which results in the need to disassemble and assemble the screws many times during subsequent maintenance, repair or replacement, which is very cumbersome. If the screws are rusted, the disassembly and assembly of the key switch is even more inconvenient.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a push button switch that is easy to disassemble, comprising:

[0006] A key switch body, wherein a limit seat is arranged at the upper end of the key switch body, and disassembly slots are arranged at both the front and rear sides of the lower end of the limit seat;

[0007] An elastic card plate, the upper end of which is V-shaped, the lower end of which is correspondingly arranged at the front and rear sides of the lower end of the key switch body through a connecting block, and positioning card platforms are evenly distributed on the outer side of the upper end of the elastic card plate;

[0008] Conductive connectors, two of which are symmetrically distributed at the front and rear ends of the bottom of the key switch body, and a connecting groove is provided on the inner surface of the middle end of the conductive connector.

[0009] Preferably, a locking groove is provided on the inner surface of the lower end of the conductive connector, and a positioning tooth is provided on the bottom of the inner side of the locking groove. The front and rear sides of the upper end of the conductive connector are movably connected with movable pin rods, and the side of the movable pin rod away from the conductive connector is fixedly connected with an L-shaped connecting arm, and the inner side of the L-shaped connecting arm is fixedly connected with a positioning pressure plate, and the middle end of the positioning pressure plate close to the conductive connector is fixedly connected with a positioning tooth block and an elastic tooth member in sequence from top to bottom.

[0010] Preferably, the longitudinal section of the positioning tooth block is a right triangle, and a plurality of positioning pressing teeth are equidistantly distributed on the inclined surface of the positioning tooth block.

[0011] Preferably, the elastic tooth piece is in the shape of an elongated strip, and the elastic tooth piece and the locking groove are matched in width.

[0012] Preferably, there are a plurality of positioning teeth, and the longitudinal section of the positioning teeth is a right triangle, and the positioning teeth and the elastic toothed member are engaged with each other.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model provides an elastic card plate. When the lower end of the key switch body passes through the thin plate with the through slot, the V-shaped elastic card plate at the upper end is deformed by the extrusion force. After the elastic card plate passes over the thin plate with the through slot, the elastic card plate is reset. At the same time, the bottom of the limit seat contacts the top of the thin plate with the through slot. At this time, the reset elastic card plate can abut against the bottom of the thin plate with the through slot with the assistance of the positioning card table, thereby realizing the rapid installation of the key switch body.

[0015] 2. The utility model provides a disassembly slot. By inserting two flat-blade screwdrivers into the disassembly slots of the limit seat respectively, the key switch body can be tilted up to move upward, thereby forcing the elastic card plate to be deformed after being squeezed again. After the elastic card plate passes through the through slot of the thin plate, the key switch body can be quickly disassembled. BRIEF DESCRIPTION OF THE DRAWINGS
