DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 5 In the embodiment of the utility model, a micro switch with high safety includes a micro switch body 1, a touch plate 2 and a pressure plate 3 are installed on the upper end of the micro switch body 1, an anti-mistaken touch mechanism 4 is arranged below the touch plate 2, an anti-impact mechanism 5 is arranged on the outer side of the micro switch body 1, and the anti-mistaken touch mechanism 4 includes a limit baffle 401, a mounting plate 402, a support plate 403 and a rubber pad 404, a support plate 403 is arranged below the limit baffle 401, and the support plate 403 supports the limit baffle 401 , a rubber pad 404 is fixedly installed on the inner wall of the limit baffle 401, a mounting plate 402 is fixedly installed on the left end of the micro switch body 1, and a limit baffle 401 is fixedly installed on the lower end of the mounting plate 402. The anti-false touch mechanism 4 also includes a spring seat 405, a buffer spring 406 and a pad 407. The upper end of the micro switch body 1 is fixedly installed with a spring seat 405, the upper end of the spring seat 405 is fixedly installed with a buffer spring 406, and the upper end of the buffer spring 406 is fixedly installed with a pad 407;

[0024] Through the reverse thrust of the spring, the user needs to apply a certain amount of pressure to achieve the switching effect, which greatly reduces the possibility of the user accidentally touching the micro switch. At the same time, the reverse thrust of the spring can also enhance the reliability of the micro switch, because the micro switch can only work normally when the user explicitly applies pressure. The rubber pad 404 provides friction resistance, so that the user needs to overcome this friction when pressing the micro switch, further reducing the possibility of accidental touching.

[0025] The anti-impact mechanism 5 includes a mounting column 501, a support rod 502, a protection grid 503, a side wall guard plate 504 and a bottom guard rod 505. The mounting column 501 is fixedly mounted on the outer walls at the front and rear ends of the micro switch body 1, and the support rod 502 is fixedly mounted on the end of the mounting column 501 away from the micro switch body 1. The protection grid 503 is fixedly mounted on the support rod 502. The side wall guard plates 504 are fixedly mounted on the left and right ends of the protection grid 503. The bottom guard rod 505 is fixedly mounted on the lower end of the protection grid 503.

[0026] The main function of the mounting column 501 is to fix and support other parts to ensure the stability of the entire anti-impact mechanism 5. The support rod 502 can transmit and disperse the impact force to protect the micro switch from external impact. The protective grid 503, the side wall guard plate 504 and the bottom guard rod 505 can provide a certain degree of protection to prevent direct impact of external objects on the micro switch.

[0027] The working principle of the utility model is as follows: the micro switch is additionally provided with an anti-mis-touch mechanism 4 and an anti-impact mechanism 5. When using the micro switch body 1, if the user needs to press the micro switch body 1, a downward force needs to be applied to the touch plate 2, and the downward force needs to overcome the friction resistance of the rubber pad 404 in the anti-mis-touch mechanism 4 and the reverse thrust of the buffer spring 406, so as to avoid the user's mis-touch, and ensure the rigor and reliability of the use of the micro switch body 1. Before installing the micro switch body 1, in order to ensure the safety of the micro switch body 1, the anti-impact mechanism 5 needs to be mounted on the micro switch body 1. The anti-impact mechanism 5 does not affect the micro switch body 1. Under the premise that the micro switch body 1 works normally, the micro switch body 1 can also be effectively protected; the anti-mistouch mechanism 4 uses a spring to provide a reverse thrust and rubber to provide a friction force, which effectively avoids the occurrence of mistouch. When pressing the micro switch, a certain pressure needs to be applied to achieve the switching effect, which effectively reduces the possibility of users accidentally touching the micro switch and improves the practicality and reliability of the micro switch. The anti-impact mechanism 5 sets up a protective frame outside the micro switch, which uses plastic materials such as polypropylene, which can not only provide protection and pressure resistance, but also has good electromagnetic shielding, effectively improving the overall reliability and safety of the micro switch.
