Problems solved by technology

This design has the following deficiencies: First, due to the existence of two positioning columns, the overall thickness of the reset mechanism is very thick, which in turn leads to a relatively thick overall thickness of the mechanical switch, making it inconvenient to apply to notebook keyboards and other devices requiring ultra-thin design
Second, the design uses a positioning column to support the shaft core at a single point. When pressing the middle of the button and around the button, different hand feelings will be produced, which will affect the comfort of the user.
Third, after long-term use, due to the small range of force points, the shaft core will produce a seesaw phenomenon after being stressed
At the same time, because the positioning column occupies the middle position, the existing reset mechanism and the mechanical switch composed of it can only be installed with light-emitting LED lights on the side, so that the light transmission to the keyboard keycap is uneven

Abstract

The invention belongs to the field of mechanical keyboard equipment, and provides an ultrathin reset mechanism of a small mechanical switch, and a small mechanical switch formed by the ultrathin reset mechanism. The ultrathin reset mechanism is mainly formed by a base whose upper surface is provided with a second spring fixing circular groove, a central spindle whose lower surface is provided with a first spring fixing circular groove, and springs in the two spring fixing circular grooves. The small mechanical switch is mainly formed by the ultrathin reset mechanism, a static terminal, and a movable terminal. Beneficial effects of the ultrathin reset mechanism and the small mechanical switch are that thickness is ultrathin, the ultrathin reset mechanism can be applied in laptop keyboard and other ultrathin equipment occasions, stress of the central spindle is uniform and consistent, and seesaw phenomenon would not occur, user experience is better; an LED lamp is on the middle position, and light casting is more uniform, and added light-transmitting lens has effects of gathering light and scattering light more uniformly; a simple and stable contact method of the movable terminal and the static terminal is provided; and the whole device is higher in stability.

Description

technical field [0001] The invention belongs to the field of mechanical keyboard equipment, and in particular relates to an ultra-thin reset mechanism of a small mechanical switch and a small mechanical switch composed of the ultra-thin reset mechanism. Background technique [0002] A mechanical keyboard is a keyboard with a strong sense of keystrokes and a good experience. Each of its buttons is controlled by a separate mechanical switch. The resetting mechanism of existing mechanical switch is mostly made up of parts such as base, spring positioning post fixed on the base, spring, shaft core, and the bottom of shaft core is also provided with spring positioning post. This design has the following deficiencies: First, due to the existence of the two positioning columns, the overall thickness of the reset mechanism is very thick, which in turn causes the overall thickness of the mechanical switch to be relatively thick, making it inconvenient to apply to notebook keyboards ...
