Problems solved by technology
The existing micro switch has a short stroke and no operating feel, and because the internal terminal switching shrapnel has a certain rebound force, a slight deviation in the component design will lead to the problem of unstable contact
On the other hand, the pressing force is not easy to control, and repeated over-forced operations may cause the switch to fail

Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0022] Such as Figure 1-3 In the illustrated embodiment, the micro switch includes an outer casing 1 , an inner casing 6 , a first terminal group 2 , a button transmission mechanism, a shrapnel transmission mechanism, and a second terminal group 5 .
[0023] The shrapnel transmission mechanism 4 , the second terminal group and the inner casing 6 form a sub-micro switch, and the sub-button 7 is pierced on the casing 6 . The second terminal group consists of a terminal 21 and a terminal 22 arranged side by side. The two terminals are installed in the base 9 . The upper part of the terminal 21 is provided with a bifurcation. The elastic piece 41 is arranged laterally on the terminal 21 , one end and the middle part are respectively sleeved on the two upper forks of the terminal 21 , and the other end is provided with a contact. The first terminal group is com...

Abstract
The invention relates to a long-stroke microswitch. The long-stroke microswitch comprises an outer shell, a first terminal set, a second terminal set, a button transmission mechanism, an elastic sheet transmission mechanism connected with the button transmission mechanism and the like, the first terminal set, the second terminal set, the button transmission mechanism, the elastic sheet transmission mechanism and the like are arranged in the outer shell, the button transmission mechanism comprises a first button and a first spring limited between the bottom of the first button and the outer shell, a transverse pressing portion is arranged on the side wall, in the outer shell, of the first button, and the pressing portion is located above the elastic sheet transmission mechanism. The button is pressed, the first spring is deformed, the button transmission mechanism transmits the pressing motion to the elastic sheet transmission mechanism through the pressing portion, then the terminal connecting relation in the second terminal set is changed, the terminal connecting relation in the first terminal set is changed, and finally electrical connection control over an external circuit is achieved. According to the microswitch, dual pressing transmission processing is adopted, the stroke capable of being set is long, the pressing hand feeling is increased, damage caused by improper operations to the microswitch is buffered, resetting is reliable, and the overall cost of the microswitch is low.
Description
technical field [0001] The invention relates to a micro switch. Background technique [0002] As the name suggests, the micro switch is a switch with a small stroke. Compared with the roller type and direct-acting limit switch, the micro switch has a small action stroke, high positioning accuracy, and usually a small contact capacity. The waterproof and stroke of the micro switch has always been a concern of the industry. The existing micro switch has a short stroke and no operating feel, and because the internal terminal switching shrapnel has a certain rebound force, a slight deviation in the component design will lead to the problem of unstable contact. On the other hand, the pressing force is not easy to control, and repeated over-forced operations may cause the switch to fail. Contents of the invention [0003] In order to solve the above problems, the present invention provides a long-stroke micro switch with stable performance. [0004] The technical solution ad...
