Keyboard

A key pressing mechanism comprises: a mounting plate 5030; a first lever 5010 attached to the mounting plate at a first plate mounting point 5014; and a second lever 5020 attached to the mounting plate at a second plate mounting point 5024. The first and second levers are joined by a neck 5040 and can rotate about their respective plate mounting points. Neck 5040 may: elastically deform when the levers rotate; have a smaller cross section than the levers; be integral with the levers; comprise a lower stiffness material than the levers; and provide a resistant force to pressing the key 2050 that may provide an audible sound or a change in feel as the key is depressed. Plate mounting points 5014, 5024 may: be along an edge of the respective levers; comprise a material of different stiffness or cross section to the remainder of the lever; and provide a resistive force to pressing the key. Key cap 2050 may comprise mounting points (fig 19, 2052) for the levers and a conductive protrusion (fig 19, 2054) to activate a key sensor that can be a touch sensor, a proximity sensor or a capacitive sensor.
