Abstract
A multiple-key unit is provided that includes a top portion, a base portion and a support mechanism. The support mechanism is provided with a body portion and a substantially U-shaped wire. The U-shaped wire includes a cross-part and two free ends that are inwardly bent and are parallel to the cross-part of the wire. The cross-part of the U-shaped wire is rotatably supported in a bearing in an eccentric manner at the key top and is parallel to the central, longitudinal axis of the key top. An assembly stop extends from the bearing and maintains the U-shaped wire, during assembly, in an oblique assembly position. Moreover, wire guides are provided in the cross-sides of the key base to vertically receive the free ends of the U-shaped wire during assembly, and in which wire guides the free ends are horizontally displaceable when the key is actuated.
