[0007] By adopting the above technical solution, the arrangement of the first inclined plate makes it easier to move the cover plate.

[0008] Preferably, a second inclined plate tilted relative to the main board is integrally connected to the other side of the main board, and a transverse plate is integrally connected to the side of the second inclined plate away from the main board.

[0009] Preferably, a metal terminal is installed in the base, a spring is provided above the metal terminal, a switch body is provided above the spring, and a second through-groove for accommodating the switch body is formed through the cover.

[0010] As a further solution of the present invention: the foot plane of the metal terminal and the base are suspended in the air, and the suspension distance is set to 0.1 mm.

[0011] By adopting the above technical solution, reliable welding is ensured, tin overflow during reflow is prevented, and switch performance is guaranteed.

[0012] As a further solution of the present invention: the base includes a receiving groove for placing the switch body, the base is provided with a limiting groove located on the side of the receiving groove and connected to the receiving groove, and the side of the switch body is integrally connected with a limiting block located in the limiting groove.

[0013] By adopting the above technical solution, the limiting block is located in the limiting groove, an anti-rotation structure is added, and production efficiency is improved.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The protrusion is located in the first through groove, allowing the cover to be clamped with the base. The setting of the ladder-shaped block increases the connection strength between the cover and the base. The riveting makes the cover strong, ensuring the normal function of the product and preventing the cover from loosening after welding. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In the embodiment of the present utility model,

[0022] A touch switch, such as Figure 1-Figure 3As shown, it includes a base 1, a cover plate 2 is provided on the top of the base 1, the cover plate 2 is provided with a first through groove 3 penetrating the cover plate 2, the base 1 is integrally connected with a protrusion 4 at the first through groove 3, one side of the protrusion 4 is riveted with a recessed groove 5, and one side of the protrusion 4 is integrally connected with a ladder block 6.

[0023] The cover plate 2 includes a main plate 18 and a first side plate 7 integrally connected to one side of the main plate 18 . A first inclined plate 8 inclined relative to the first side plate 7 is integrally connected to the side of the first side plate 7 away from the main plate 18 .
