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