ABSTRACT:
The present invention relates to a keyboard button structure. Each button has a pair of side mounted "U" shaped plates. Holes are provided in the housing panel and protrusions are formed inside the holes to permit rapid assembly of the button into the holes, and to prevent loss of buttons. A rubber member between the button and the panel provides button return and also permits feel of the contact and comfortable operation. The invention's novel structure provides economic and other advantages.
