Mechanical switch structure

Abstract

A mechanical switch structure comprises a key cap, a substrate with a guiding opening, an elevating unit arranged between the key cap and the substrate and an accommodation casing connected to the lower of the substrate. The accommodation casing comprises first and second accommodation units; a guiding unit is accommodated in the first accommodation unit along the key cap pressing direction; a segment difference part is formed in the surrounding the guiding unit; the first elastic assembly provides an elastic force of the guiding unit; a resistance module includes a push-abutting unit and a second elastic assembly, the push-abutting unit abuts against the segment difference part of the guiding unit, and the segment difference part is of a fluctuating shape facing the push-abutting unit; the second elastic assembly provides the push-abutting unit with an elastic force towards the guiding unit; and the push-abutting unit abuts against the segment difference part so that the key cap provides different resistances in the pressing process.

Description

technical field [0001] The invention relates to a mechanical switch structure, in particular to a mechanical switch structure for inputting signals or instructions by pressing keys, which can be applied to computer keyboards. Background technique [0002] The keyboard is already a very popular computer peripheral device, which can be divided into a mechanical keyboard and a membrane keyboard. In the membrane type keyboard, a scissor foot support, an elastic component, and a thin film circuit layer are arranged on the bottom of the keyboard under the keycap. After the keycap is pressed, the elastic component is driven by the keycap and triggers the thin film circuit layer downwards to generate a signal, that is, an output signal is completed. The disadvantage of the membrane keyboard is that when the trigger circuit under a single key is damaged, the thin film circuit layer must be replaced or may not be repaired, and it cannot be replaced for a single key. Its operating fe...

Problems solved by technology

The disadvantage of the membrane keyboard is that when the trigger circuit under a single button is damaged, the membrane circuit layer must be replaced or may not be repaired, and it cannot be replaced for a single button

Its operating feel depends on the elastic components, and the short travel of the keys results in a poor pressing feel, which is worse than that of a mechanical keyboard.
