Abstract

A keyboard having a plurality of contactless switches, the keyboard includes a signal conversion circuit allocating an input signal line from a control device and an output signal line to the control device for each operating switch of the contactless switches, wherein the signal conversion circuit is configured to output the signal of the input signal line allocated to the operating switch to the output line allocated to the operating switch when the contactless switch is operated.

Claims

1. A keyboard having a plurality of contactless switches, the keyboard comprising:

a signal conversion circuit allocating an input signal line from a control device and an output signal line to the control device for each operating switch of the contactless switches;

wherein

the signal conversion circuit is configured to output the signal of the input signal line allocated to the operating switch to the output line allocated to the operating switch when the contactless switch is operated.

2. A keyboard according to claim 1 wherein the signal conversion circuit comprises a PLD, the PLD being a programmable IC.

3. A keyboard according to claim 1 wherein the plurality of contactless switches are provided on a film attached on a screen of a display unit.
