摘要: A low profile keyboard switch with tactile feel and short key travel is disclosed. The may be a matrix connected includes lower, fixed contact an upper, concave contact. supported at one end operates as cantilever beam. When pressure applied by key, the unsupported to cause buckling of its end, electrical made lower contacts possess return force snap action desirable for low-profile, low-cost switch.
