Abstract

Erfindungsgemäß wird eine elektrische Kontaktierungseinrichtung mit elektrischen Kontaktstellen (11) auf einem beweglichen Träger (10) und mit diesen gegenüberliegenden Festkontakten geschaffen, die nach einer Schaltbewegung des Träges (10) die Kontaktstellen (11) kontaktieren. Um mehrere galvanisch getrennte Kontakte zu schaffen, werden die Kontaktstellen (11) gegenseitig derart isoliert, dass sie zueinander und/oder zum Träger (10) unterschiedliche Potenziale ermöglichen. Des Weiteren wird eine besonders geeignete Tastatur (30) angegeben, mit mindestens einem ersten Tastenfeld (32), welchem eine derartige elektrische Kontaktierungseinrichtung zugeordnet ist, und mindestens einem zweiten Tastenfeld (31), dessen zugeordneter Taster (36) schaltblasenartig ausgeführt ist oder ein durch ein Schnappelement (38) vermitteltes Sprungschaltverhalten aufweist.

Figure 00000001
According to the invention, an electrical contacting device with electrical contact points (11) is created on a movable carrier (10) and with fixed contacts opposite these, which contact the contact points (11) after a switching movement of the support (10). In order to create a plurality of electrically isolated contacts, the contact points (11) are mutually insulated in such a way that they enable different potentials from one another and / or from the carrier (10). Furthermore, a particularly suitable keyboard (30) is specified, with at least one first keypad (32), to which such an electrical contacting device is assigned, and at least one second keypad (31), the associated push button (36) of which is designed as a switching bubble or by a snap element (38) has switched switching behavior.
