Abstract
A universal circuit board compatible for a mechanical keyswitch and an optical keyswitch includes a main body, a plurality of conductive terminals and an opening structure. The main body has a first surface and a second surface opposite to each other. The plurality of conductive terminals is disposed on the first surface of the main body. The opening structure is formed on the main body and pierces through the first surface and the second surface. The opening structure can be inserted by an axle body of the mechanical keyswitch or be an optical transmission channel of the optical keyswitch.
