Abstract

The invention discloses a PCB (Printed Circuit Board) of a digital coding switch and the digital coding switch with the PCB. The digital coding switch with the PCB comprises a handle device, a rotating shaft, a rotating shaft angle positioning mechanism, a shell, the PCB and a turntable with contacts. Since the rotating shaft angle positioning mechanism with a gear ring wheel outside and balls inside is adopted, the PCB adopts a technological method of firstly etching a circuit and then plating gold, and a coding disc is designed according to the frequency and simplicity degree of the change of the same data location by adopting a principle that data bits which change the most frequently are designed on the outermost ring of the PCB and data bits which change simply are designed on the innermost ring of the PCB, the PCB of the digital coding switch and the digital coding switch with the PCB have the advantages that the operation comfort is improved, the rotating resistance is reduced, the product life is effectively prolonged, the coding accuracy is greatly improved and the like.

Description

technical field [0001] The present invention is applied to the digital coding switch on the human-machine interface of numerical control and automation equipment; especially relates to the method of using machinery to output a group of digital signals for computer, PLC identification, does not contain electronic components (such as: resistors, capacitors, inductors and semiconductors) Components, etc.) digital encoding switch PCB board and digital encoding switch containing it. Background technique [0002] Such products on the existing market have defects such as poor operating experience, short life, and high output coding error rate. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned shortcomings of the prior art, mainly to improve the operating comfort and reduce the rotational resistance, effectively prolong the product life, and greatly improve the coding accuracy, by adopting a more optimized structure and manufac...
