Description

Button switch structure

technical field

The utility model relates to a button switch structure, in particular to a function of internally setting springs, extension springs and guide posts to achieve the positioning of the switch structure and preventing tilting during action, so that the switch structure can smoothly conduct loops, close loops and input Signal button switch structure.

Background technique

The general switch structure is used to conduct or close the circuit. Different structures have different conduction methods, such as pressing, button turning, pulling, etc. Among them, the pressing method is the most common because of its convenient conduction. In this way, with several keys of the same or different shapes, various signals can be input and predictable actions can be performed.

As far as the structure of the button structure is pressed, the button structure of the pressing action is usually provided with a base or an outer casing, and the inner casing or internal action components and the base or the outer casing are usually designed with an appropriate gap, so that the button can be used. Smooth reciprocating movement, but also because of the existence of this gap, the direction of force applied must be perpendicular to the plane of the button during operation. If the direction of force is shifted, the inside of the button structure will easily get stuck and cannot be turned on or off Loops, or repeated input of the same signal, cause a lot of trouble when an emergency occurs. The above-mentioned defects in the existing switch structure and function can no longer meet the needs of today's users, and need to be further improved.

Utility model content

The purpose of this utility model is to provide a button switch structure to solve the above-mentioned various situations and problems, integrate the above-mentioned conventional structure and other deficiencies, so that the button structure can move back and forth smoothly when in use, and avoid inclination. In the case of jamming, set the conductor, several terminals, terminal support plate, spring, tension spring and curved plate on the base, the action component is set in conjunction with the base, and supports the transparent cover and the fluorescent plate, and the outer shell is fixed on the base and the action outside of the component.

A button switch structure of the utility model is realized by adopting the following technical means:

A push button switch structure, wherein the base is provided with guide rod slots, several perforations and protrusions; an upper terminal and a lower terminal are arranged in the perforations of the base; the terminal support plate is provided with V-shaped openings on both sides, Set in the perforation of the base; set a curved plate and a conductor at the V-shaped opening of the terminal support plate; connect the curved plate and the conductor by a tension spring; set a light-emitting component in the center of the base; The oblique cone is perforated, with several guide pillars on the upper end and guide rods on the lower end, which are matched with the guide rod slots of the base and set on the base; a spring is installed on the protruding column supporting the action component of the base; a central setting on the upper end is fixed on the base An outer casing with perforations; a fluorescent plate is arranged on the upper end of the action component; a transparent cover is arranged on the fluorescent plate in cooperation with the fluorescent plate.

Several guide pillars arranged on the upper end of the aforementioned action assembly are semi-cylindrical.

Compared with the prior art, the button switch structure of the present utility model has the following obvious advantages and beneficial effects:

The button switch structure of the utility model mainly uses the action components to press down the curved plate, and the curved plate and the conductor are connected by a tension spring, and they are all arranged on the terminal support plate. The pressure makes the tension spring stretch and the conductor is pressed down so that it contacts the lower terminal to conduct the circuit, and then returns to the original position by the reaction force of the spring, and the action component moves up and down in the process of reciprocating, because of the gap between it and the outer shell , when receiving a non-vertical downward external force, there will be a horizontal component force, which is often prone to tilting and stagnation. Therefore, a semi-cylindrical guide post is provided on the outer periphery of the action component. When the external force acts, the guide post is in contact with the outer shell so that the action components will not tilt. In addition, because the semi-cylindrical guide post is in contact with the outer shell, the contact between the semicircular curved surface and the plane is a line contact, and the contact area is small. Not only It achieves the functions of positioning and anti-tilting, and will not hinder the reciprocating movement of the action components due to the large contact area.
