Problems solved by technology

If the optical key is to be installed on the traditional circuit board 72, the internal component design of the key 70 needs to be redesigned, for example, the position of the key cap and the elastic support below it should be moved up, so as to make room for placement in the key body structure. Light sensor, so users cannot conveniently remove and replace buttons of different specifications on traditional circuit boards

Abstract

The invention discloses a universal circuit board compatible with a mechanical key and an optical key. The universal circuit board comprises a body, a plurality of conductive contacts and an opening structure; the body has a first surface and a second surface opposite to the first surface; the plurality of conductive contacts are disposed on the first surface of the body; the opening structure isformed on the body and penetrates the first surface and the second surface; and a shaft of the mechanical key or an optical signal transmission channel formed on the optical key can be inserted into the opening structure.

Description

technical field [0001] The invention provides a circuit board for installing keys, especially a general circuit board compatible with mechanical keys and optical keys. Background technique [0002] see Figure 7 , Figure 7 It is a schematic diagram of the assembly of the button 70 and the circuit board 72 in the prior art. The traditional circuit board 72 is a solid board with several transmission terminals 74 arranged on the upper surface. The button 70 is disposed on the circuit board 72 , and the elastic triggering part 76 of the button 70 abuts against the transmission terminal 74 . When the keycap 78 is pressed and moves down, the keycap 78 drives the elastic trigger member 76 to deform, thereby forming a conductive path to generate a trigger signal, and sends the trigger signal through the transmission terminal 74 for analysis and interpretation by the signal processor; The button 70 of the aspect belongs to a mechanical button. If the optical key is to be installe...
