Abstract

The invention discloses an inductance type key keyboard which comprises a keyboard body. A PCBA board is arranged on the keyboard body, a plurality of key devices are arranged on the PCBA board, each key device is provided with an inductance type limit switch and a crystal triode, and the key devices are provided with induction pieces used for triggering the inductance type limit switches. And each inductance type limit switch is electrically connected with the PCBA board through a corresponding crystal triode. The invention is applied to the technical field of keyboards.

Description

technical field [0001] The invention relates to the technical field of keyboards, in particular to an inductive key keyboard. Background technique [0002] In the prior art, the traditional keyboard uses a mechanical shaft or a conductive film as a conduction button, which has a complex structure and high manufacturing cost, is not suitable for mass installation and use, and is easily disturbed by the working environment. After a long time of use, the key response becomes poor. So sensitive. Contents of the invention [0003] (1) Technical problems to be solved [0004] An inductive keypad solves the technical problems of complex structure, high manufacturing cost, unsuitability for mass installation and use, insensitive key response, weak anti-interference ability, and short service life. [0005] (2) Technical solutions [0006] In order to solve the above-mentioned technical problems, the present invention provides an inductive keypad, comprising a keyboard body, a P...
