Miniature switch panel with operating device

摘要

A miniature switch panel (1) with pin-shaped manual operating device (8) is to be designed for being able to be installed operationally reliably in extremely flat terminals as have already been proposed by cheque or credit cards (19) with electronic circuit for data processing. For this purpose, the switch panel (1) consists of a grouping of optical sensors (4) whilst the operating device (8) exhibits an optical transmitter (9) which, when pressed into an orientation depression (3) is switched on via an individual optical sensor (4). The risk of improper operation of the switch panel (1) is significantly reduced by the fact that a particular operating device (8) with modulated energy radiated by the transmitter (9) is associated with a particular card (19) with a demodulator for this identification. <IMAGE>
