Abstract (en)
[origin: EP0544124A2] Obliquely downwardly running spring arms are integrally formed on the individual push-button keys. The lower ends of these spring arms are connected via tapers to connecting webs. As a result of the tapers, the weak point of this arrangement comes to rest such that the operation of the individual keys is maintained in the event of a fracture in the installed state. <IMAGE>
