[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] like Figure 1-3As shown, a manufacturing process and contact travel angle optimization structure based on a limit switch includes a housing 1. The housing 1 is provided with a fixing seat 2, a fixing screw sleeve 3, a micro switch 4, and a connecting through hole 5. The fixing seat 2 is integrally formed and symmetrically connected to the middle of both ends of the bottom of the housing 1, and a fixing through groove 6 is opened in the middle of the fixing seat 2. The fixing screw sleeve 3 is pre-embedded at the top corner of the housing 1. The micro switch 4 is symmetrically installed and fixed inside the housing 1 at the rear right end by screws. The connecting through holes 5 are symmetrically opened at the middle of the front and rear ends of the housing 1. An operating shaft 7 is rotatably connected to the connecting through hole 5. A hexagonal shaft is integrally formed at the rear end of the operating shaft 7. 8. A first cam 9, a second cam 10, and a spring seat 11 are provided on the hexagonal shaft 8. The first cam 9 is fixed to the rear end of the hexagonal shaft 8 by screws. The second cam 10 is fixed to the middle section of the hexagonal shaft 8 by screws. The spring seat 11 is fixed to the front end of the hexagonal shaft 8 by screws. A torsion spring 12 is fixed to the front end of the spring seat 11 by screws. The front end of the torsion spring 12 is fixedly connected to the inner front wall of the housing 1. The first cam 9 and the second cam 10 are staggered and respectively fit with the corresponding micro switch 4. The housing 1 is processed by molding in one piece.

[0016] Specific usage: Turning the operating shaft 7 to the left drives the hexagonal shaft 8 to rotate to the left. The rotation of the hexagonal shaft 8 to the left drives the first cam 9, the second cam 10, and the spring seat 11 to rotate to the left simultaneously. The first cam 9 rotates to the left and keeps in contact with the micro switch 4 at the rear end. The second cam 10 rotates to the left and squeezes the micro switch 4 at the front end. At this time, the micro switch 4 at the front end is activated. The spring seat 11 rotates to the left and compresses the torsion spring 12. At the same time, the torsion spring 12 limits the rotation angle of the spring seat 11 to a maximum of 90°. When it is necessary to activate the micro switch 4 at the rear end, the operating shaft 7 is turned in the opposite direction. Its operating principle is the same as described above.

[0017] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
