Abstract: A low profile tactile keyswitch including a horizontally positioned elastic column spring which buckles under an axial load to provide a tactile feel for the keyswitch. The ends of the spring are maintained between two spring holders which are urged together as the keybutton is depressed. Stabilizing arms pivotally attached to the keybutton are used to stabilize the keybutton and also to carry extensions which engage the spring holders to move them together as the keybutton is depressed. The keyswitch is operable to be placed in an inactive configuration in which the keybutton is lowered without placing the spring under added compression.
