Problems solved by technology

Ordinary mechanical switches generate signals by pressing down on the structure to make the metal contacts open / close. However, the metal contacts are made of metal, and the surface will be oxidized, resulting in signal jitter and delay when the metal contacts are in contact. Time phenomenon, which forces the signal to be delayed and anti-shake during program design, and the response speed will slow down, otherwise signal input errors will occur, and the signal response will not be fast and agile; the photoelectric mechanical switch is through a light emitting element and a light The receiving element uses light conduction to generate signals, but the process of light conduction is easily affected by other light or dust, and is not resistant to vibration, which makes the light prone to jitter, error input or unresponsiveness, etc.

Abstract

A keyboard switch, and keyboard. The keyboard switch comprises a stem (10), a PCB board (30), and at least one inductor or at least one Hall element (31) provided on the PCB board (30). The stem (10) is provided with at least one metal member (11) spaced apart from the inductor or Hall element (31). When the stem (10) is pressed, the metal member (11) approaches the inductor or Hall element (31), and the keyboard switch generates a turn-on signal. By applying the principle of an inductive proximity switch to the keyboard switch, the present invention enables the keyboard switch to have advantages such as a simple structure, a rapid response, superior interference immunity, vibration endurance, resistance to dust, stable performance, a long service life, and low power consumption.

Description

technical field [0001] The invention relates to the technical field of keyboards, in particular to a keyboard switch and a keyboard using the keyboard switch. Background technique [0002] At present, conventional keyboard switches include ordinary mechanical switches and photoelectric mechanical switches. Ordinary mechanical switches generate signals by pressing down on the structure to make the metal contacts open / close. However, the metal contacts are made of metal, and the surface will be oxidized, resulting in signal jitter and delay when the metal contacts are in contact. Time phenomenon, which forces the signal to be delayed and anti-shake during program design, and the response speed will slow down, otherwise signal input errors will occur, and the signal response will not be fast and agile; the photoelectric mechanical switch is through a light emitting element and a light The receiving element uses light conduction to generate signals. However, the light conductio...
