Due to the existence of the push rod oblique section, the two elastic conductive sheets can be smoothly gathered together to form a passage; at the same time, the device has a simple structure, low cost, linear feedback, and high reliability.

A limiting countersunk hole 15 with a countersunk hole structure is integrally arranged on the bottom surface of the base 14. The limiting countersunk hole 15 is arranged corresponding to the push rod slider 8, and the limiting countersunk hole 15 is located at the extreme position of the downward movement of the push rod slider 8 to accommodate the push rod slider 8.

[0025] The push rod slider 8 is integrally formed with the push rod 2, and slideways are provided on both sides of the push rod slider 8 to assist the lifting and lowering movement of the push rod slider 8. The bottom surface of the card slot 4 is integrally provided with a slider guide rod 9, and a through hole is provided at the push rod slider 8 corresponding to the slider guide rod 9, and the push rod slider 8 moves relative to the slider guide rod 9 through the through hole.

[0026] The base 14 is provided with a spring clamping plate 12, on which a dynamic spring 10 and a static spring 11 are clamped and fixed respectively. The dynamic spring 10 and the static spring 11 are connected with corresponding wires at the position of the wire clamp interface 7. The dynamic spring 10 and the static spring 11 have two free ends in the direction of the push rod slider 8, and a gap is left between the two free ends to form a normally open contact. The dynamic spring 10 moves in the direction of the static spring 11 under the action of the push rod slider 8, and contacts with the static spring 11 to conduct the ignition circuit.

[0027] Example 2

[0028] See also Figure 4 , continue to see Figures 1 to 3 , an ignition switch used for a fuel appliance, the free end of the movable spring piece 10 has a top bending section 17, a first bending section 18, and a second bending section 16, the free end is bent upward through the first bending section 18, and is bent toward the direction of the push rod slider 8 through the second bending section 16 so as to contact the push rod slider 8 and move toward the static spring piece 11 under the drive of the push rod slider 8.

[0029] The top of the moving spring 10 is bent away from the moving spring 10, and the convex end formed by the bending faces the static spring 11. Under the drive of the push rod slider 8, the top bending section 17 contacts the static spring 11 to achieve the conduction of the circuit.

[0030] The base 14 is provided with a plurality of hooks 5 distributed around the circumference thereof, the hooks 5 correspondingly engage with the slots 4, and the slots 4 are distributed around the circumference of the cover 1. The structure and connection relationship of the remaining parts are the same as those described in any one of the aforementioned embodiments, and will not be described here in order to avoid cumbersome text.

[0031] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles played by the technical features in the present technical solution, so as to help technicians in this field to fully understand the technical solution and reproduce it.

[0032] In the present application, the cover body 1 and the clamping ring 3 form an integrated structure, the clamping ring 3 is clamped on the corresponding gas valve, the cover body 1 can protect the top opening of the base 14, and fix the push rod slider 8 between the cover body 1 and the base 14.

[0033] The base 14 and the cover 1 are connected by a snap-fit ​​connection, which is a conventional detachable connection method. Those skilled in the art will appreciate that detachable connection methods, such as screw connection, adhesive connection, etc., can replace the above connection methods.

[0034] The base 14 described in the present application is provided with wire clamp interfaces 7 on both sides, and the wire clamp interfaces 7 on the same side of the base 14 are arranged in pairs, so that two wires can be inserted and pulled out. One of the wires is clamped with the tail end plates of the moving spring piece 10 and the static spring piece 11 respectively during the process of passing through the wire clamp interface 7, and the tail end plates of the moving spring piece 10 and the static spring piece 11 are processed with clamping ports.

[0035] The movable spring 10 and the stationary spring 11 are respectively clamped and fixed on the spring clamping plate 12 , and the spring clamping plate 12 and the base 14 form a whole.

[0036] The movable spring piece 10 and the static spring piece 11 form a normally open contact structure in the direction toward the push rod slider 8. The movable spring piece 10 has a second bending section 16, a top bending section 17, and a first bending section 18. The second bending section 16 is bent to form a protrusion that is bent in an arc toward the direction of the push rod slider 8, and the protrusion can cooperate with the push rod slider 8. The top bending section 17 has a protrusion formed by bending in an arc toward the direction of the static spring piece 11, and the protrusion can achieve conduction between the top bending section 17 and the static spring piece 11.

[0037] At the same time, in the above structure, the first bending section 18 can realize the deformation of the second bending section 16 and the top bending section 17 after being subjected to force, that is, when the push rod slider 8 moves downward following the push rod 2, when the push rod 2 is removed from the external force, the push rod 2 and the push rod slider 8 can be reset under the reset action of the first bending section 18. During the reset process and the downward pressing process, the push rod slider 8 realizes its own limitation through the limiting slide groove 13 and the slider guide rod 9.

[0038] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
