Abstract

It comprises a keypad assembly unit (1) and a hinged-box assembly unit (3). A coding printed-circuit board (2) is disposed between the assembly units (1, 3). Without modifying the keypad assembly unit (1) and with its assigned identical coding spring unit and identical hinged-box assembly unit (3), different dialling programs are created through selection of the coding printed-circuit board (2) and/or the associated microswitch. <IMAGE>
