Double spring unit for data input device comprises first spring which is pressable against stop and includes elastic leaf joined to elastic leaf of second spring forming acute angle with first spring

摘要

The double spring unit (2) for indirect operation of a movable element (24) in a data input device comprises a first spring with an elastic leaf (5) which is pressable against a stop (25). The end (10) of this leaf is joined to the end (11) of the elastic leaf of a second spring forming an acute angle with the first spring. The two springs are arranged so that the movable element (24) is operated by their joint zone (10, 11), or by the elastic leaf of the second spring. An Independent claim is also included for a comb-like array consisting of the proposed double spring units.
