Keyboard structure having panel mounted key actuators with electrical component operating element

A keyboard for providing an electrical output on depression of a key, said keyboard comprising a chassis and a plurality of keys, wherein each key is formed of two substantially rigid members spaced apart with facing surfaces and at least a pair of parallel spaced resilient strips lying in separate planes spaced in a direction normal to said surfaces, said strips being of equal length, each extending between said rigid members and joining said rigid members to form a parallel motion linkage, one of said rigid members being mounted on the chassis with the planes of the strip parallel to the chassis, a key top mounted on the upper end of the second of said rigid members whereby, by depression of the key top, the second of the rigid members is movable towards and away from the chassis without tilting with respect to the chassis, and an operating element on the lower end of the second rigid member arranged for co-operation with an electric circuit element fixedly located with respect to the chassis.
