[0021] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] Reference Figures 1 to 3 , an embodiment of the zipper switch of the present invention is proposed:

[0023] A zipper switch comprises a zipper switch body and a zipper switch circuit used for the zipper switch body.

[0024] The zipper switch body comprises a switch housing 1, a rotating shaft 3, a zipper 2, a first electrode sheet 4, a second electrode sheet 5, and a reset spring 6. The switch housing 1 comprises a base 12, a top cover 11, and a mesh nut 13. The top cover 11 is mounted on the base 12 and fixedly connected to the base 12 via a snap-fit ​​mechanism. A threaded post is provided on one side of the top cover 11, and the mesh nut 13 is screwed to the post. A through-hole is provided in the center of the post. One end of the zipper 2 enters the switch housing 1 through the through-hole and connects to the rotating shaft 3. A base connection slot and a base connection block are provided on the inside of the base 12. The second electrode sheet 5 is mounted in the base connection slot, and the reset spring 6 is secured to the connection block.

[0025] The rotating shaft 3 includes a rotating shaft body 32, a spring 31, a rotating shaft sleeve 34, and an intermediate gasket 33. The intermediate gasket 33 is disposed between the rotating shaft sleeve 34 and the rotating shaft body 32. A rotating shaft body connecting groove is disposed on the bottom side of the rotating shaft body 32. The first electrode plate 4 is U-shaped, with both ends of the top portion of the first electrode plate 4 positioned within the rotating shaft body connecting groove. The rotating shaft sleeve 34 holds the first electrode plate 4 in place at the bottom of the rotating shaft body 32. The spring 31 is disposed above the rotating shaft 3 inside the switch housing 1, providing a tighter connection between the rotating shaft 3 and the switch housing 1.

[0026] The zipper switch circuit includes a zipper switch S1, capacitors C3 and C4, and resistors RZ, R11, and R12. One end of resistor RZ is connected to the power supply, and the other end of resistor RZ is connected to the input / output pins of the main control chip via resistor R11. The zipper switch S1 is connected in series with resistor R12, with one end connected to ground and the other end connected to the input / output pins of the main control chip. Capacitor C4 has one end connected to resistor RZ and the other end connected to ground. Resistor R12 and capacitor C4 form a filter circuit. This filter circuit prevents jitter in the output waveform when the first electrode sheet 4 and the second electrode sheet 5 partially contact, thereby ensuring the stability of the main control chip control.

[0027] When not in use, the main control chip detects a high level on its input and output pins and charges capacitor C3 through the power supply. When in use, the zipper 2 drives the shaft 3 to rotate, causing the first electrode sheet 4 and the second electrode sheet 5 to contact. During the movement of the shaft 3, since the first and second electrode sheets 4 and 5 are not fully in contact, capacitor C3 discharges to maintain waveform stability. When the first and second electrode sheets 4 and 5 are fully in contact, a low level is output. The main control chip determines whether the zipper is pressed once or continuously by the duration of the low level, and implements different control methods based on different control information.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
