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 micro switch. The switch includes an outer casing and a first terminal group, a button transmission mechanism, a shrapnel transmission mechanism and a second terminal group arranged in the outer casing. The spring plate transmission mechanism and the second terminal group are encapsulated in a waterproof casing, and the waterproof casing is located inside the outer casing. Pressing the button, the transmission part transmits the pressing action to the shrapnel transmission mechanism, thereby changing the terminal connection relationship in the second terminal group, and then changing the terminal connection relationship in the first terminal group to finally realize the electrical connection control of the external circuit. The waterproof switch of the present invention is waterproofed inside the switch, which can effectively prevent the waterproof parts from being corroded by the environment and cause the waterproof performance to decrease, prolonging the service life of the switch; The sub-micro switch can completely adopt the existing long-stroke waterproof micro switch, which has mature technology, stable process, easy production, and achieves the dual functions of waterproof and waterproof protection.

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...
