[0033] The switch structure comprises two symmetrical switch assemblies. The two switch assemblies correspond to the two terminal assemblies respectively.

[0034] The switch assembly comprises a key 12, a sliding sleeve 13 and a lifting column 14. The sliding sleeve 13 is integrally formed at the bottom end of the key 12 and is inserted into the inner seat 2 in a sliding connection manner. The inner top wall of the sliding sleeve 13 is integrally formed with a pipe body 15 and two vertical plates 16. The bottom end of the pipe body 15 is flush with the top end of the sliding block 3. The vertical plate 16 corresponds to the extension plate 9, and the second inclined surface 17 matched with the first inclined surface 10 is arranged on the vertical plate 16. The top end of the lifting column 14 penetrates through the pipe body 15 and is fixedly connected with the pipe body 15.

The inner side wall of the inner seat 2 is integrally formed with a sliding strip for being inserted into the strip-shaped groove and sliding upward and downward along the strip-shaped groove. The stability of the sliding sleeve 13 when sliding upward and downward can be improved through the arrangement of the sliding strip and the strip-shaped groove.

[0038] Working principle:

[0039] The conduction of one terminal assembly is used for realizing the forward rotation of the motor, and the conduction of the other terminal assembly is used for realizing the reverse rotation of the motor. When one of the switch assemblies is pressed, the key 12 drives the sliding sleeve 13 to move downward. The sliding sleeve 13 drives the pipe body 15 and the vertical plate 16 to move downward. The pipe body 15 drives the lifting column 14 to move downward. After the vertical plate 16 moves downward, the second inclined surface 17 is pressed on the first inclined surface 10, and the force received by the first inclined surface 10 can be decomposed into a horizontal pushing force of the extension plate 9. Under the action of the force, the extension plate 9 is pushed to the other switch assembly, the extension plate 9 drives the sliding block 3 to push to the other switch assembly, so that the top end of the sliding block 3 is clamped below the pipe body 15 in the other switch assembly, and the other switch assembly cannot be pressed. When the lifting column 14 in the pressed switch assembly moves downward, the contact bridge 19 moves downward, the contact bridge 19 passes through the through groove and contacts the two bending parts 6, so that the two wiring terminals 5 are connected through the contact bridge 19, the terminal assembly is conducted, and the motor is started. The utility model can avoid that the two keys 12 are pressed at the same time, thereby improving the reliability of the work of the curtain switch body, and effectively avoiding misoperation.
