Problems solved by technology

On the other hand, 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 cause 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

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] 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 .

[0030] 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 microswitch. The microswitch comprises an outer shell, a first terminal set, a button transmission mechanism, an elastic piece transmission mechanism and a second terminal set, wherein the first terminal set, the button transmission mechanism, the elastic piece transmission mechanism and the second terminal set are arranged inside the outer shell. The elastic piece transmission mechanism and the second terminal set are packaged in a water-proof shell which is located in the outer shell. A button is pressed, a pressing action is transmitted to the elastic piece transmission mechanism through a transmission component so that a terminal connection relation in the second terminal set can change, and the terminal connection relation in the first terminal set changes to achieve electrical connection control of an external circuit finally. According to the water-proof microswitch, water-proof processing is conducted in the microswitch, it can be effectively prevented that a water-proof component is corroded by the environment to reduce the water-proof performance, and service life of the microswitch is prolonged; the elastic piece transmission mechanism, the second terminal set and the water-proof shell constitute a sub-microswitch which can be an existing long-stroke water-proof microswitch entirely, the technique is mature, the technology is stable, production is convenient, and water-proof and water-proof protecting effects are achieved.

Description

technical field [0001] The invention relates to the field of micro switches. Background technique [0002] The waterproof and stroke of the micro switch has always been a concern of the industry. Most of the existing micro switches are waterproofed on the outside of the switch, for example, a silicone waterproof sleeve is sleeved on the contact between the switch button and the base. Such external waterproof components are easily corroded by the environment, resulting in reduced waterproof performance. 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. On the other hand, 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 proble...
