Abstract: A low profile keyswitch for electrical keyboards is disclosed which has the capability of being operated either as a contactless analog type of keyswitch, or as a mechanical contact type of keyswitch. The keyswitch may include a pair of normally-closed contacts that are opened when a separator bar that is integrally formed in the interior of the plunger passes between the contacts as the plunger is depressed. Alternately, a permanent magnet may be carried on one side of the plunger to control the magnetic saturation state of a closed-loop magnetic core which, along with a pair of U-shaped conductive lines that thread through the core, is inserted into a retaining well formed by a pair of walls that project upwardly from a horizontal surface of the base at a location adjacent the side of the plunger that carries the magnet.
