Detailed Description

The present invention will be further described with reference to the accompanying drawings.

A magnetic Hall knob key switch can be mainly decomposed into the following 4 modules:

firstly, a first module is composed of a handle decorative shell 1; a transparent light guide ring 2; a rotating handle body 3; a handle rotation shaft 4; a first magnetic block 5; and the second magnetic block 6. The handle rotating shaft 4 component is pressed into the central position of the rotating handle main body 3 component; the magnetic blocks (defined as a first magnet) of the first magnetic block 5 and the second magnetic block 6 are pressed into the corresponding protruding installation positions in the rotating handle main body 3; the handle decorative shell 1 and the transparent light guide ring 2 are arranged on the shell of the rotary handle body 3.
