Description

TECHNICAL FIELD

[0001] The utility model relates to a touch switch technical field, concretely relates to a touch switch convenient to dismount. BACKGROUND

[0002] The touch switch is a kind of electronic switch, belongs to electronic component class.It is also called key switch, also be called sensitive switch.

[0003] The touch switch is usually composed of insert, base, spring piece, button, cover plate, wherein waterproof touch switch adds a layer of polyimide film on spring piece.The working principle is that by different operating force and operating direction, the internal metal spring piece is stressed to change to realize the on-off of circuit.When the pressure is applied to the operating direction of switch, the function of switch is closed and connected;When the pressure is removed, the switch is disconnected.

[0004] When the existing base and cover plate are installed, the insertion rod on the base is inserted into the insertion hole on the cover plate, and the insertion rod head is hot-melted to become larger by hot riveting, so as to realize the fixation between the base and the cover plate;However, this kind of way, not only is inconvenient when fixing, and when disassembling and repairing subsequently, since the insertion rod on the base has been deformed, the insertion rod head must be cut off to separate the cover plate and the base, so that the base cannot be disassembled without damage, resulting in high scrap cost of the base.

[0005] Therefore, the applicant has made beneficial design, found the method to solve the above problems, and the technical scheme to be introduced below is generated in this background. CONTENT OF THE UTILITY MODEL

[0006] The utility model provides a touch switch convenient to dismount to solve the problems in the above background technology.

[0007] To achieve the above object, the utility model provides the following technical scheme:

[0008] A touch switch convenient to dismount, including base, cover plate, the inside of base is equipped with inner chamber, the inner chamber four corners are equipped with insertion rod, the surface four corners of cover plate are all set up and are inserted into the insertion hole, the insertion rod top all rotates and is equipped with knob, the side wall of insertion hole is set up and is inserted into the through slot, the edge of insertion hole one side is equipped with limit slot, the side wall of knob is equipped with limit block, the bottom wall one side of limit slot is equipped with clamping groove, the bottom wall of limit block is equipped with convex point, the insertion rod is inserted into the insertion hole, the limit block is inserted into the limit slot, the convex point is inserted into the clamping groove.

[0009] Preferably, the inner chamber is provided with a button, a through hole is formed in the center of the cover plate, and the button top penetrates through the through hole and is located on the top of the cover plate.

[0010] Preferably, the knob has a screw block on top, and the surface of the screw block has an "I"-shaped groove.

[0011] Beneficial effects

[0012] The tactile switch that is easy to assemble and disassemble provided in this embodiment of the utility model has at least one of the following technical effects:

[0013] This utility model, through the aforementioned technical solution, allows for the following installation steps: During installation, the insert rod and knob on the base are inserted into the insertion hole on the cover plate. Rotating the knob causes the limiting block to engage with the limiting groove, and the protrusion engages with the slot, thus securing the cover plate to the base. During disassembly, rotating the knob causes the protrusion to disengage from the slot, and the limiting block to disengage from the limiting groove. Rotating the limiting block to the through groove releases the limiting fixation on the cover plate, allowing it to be removed from the base. This eliminates the need for hot riveting to secure the cover plate to the base, and disassembly does not damage the base, making fixing and disassembly more convenient and reducing the cost of base disposal.
