Claim 0:
1. An analog input device comprising:
at least one mounting panel;
a matrix of analog push button assemblies mounted to the at least one mounting panel;, a multiplexer including an input side and an output side, wherein the input side is coupled to the matrix of analog push button assemblies;, an analog-to-digital converter which is coupled to the output side of the multiplexer to convert an analog signal, from at least one of the matrix of analog push button assemblies as a measure of an amount of depression of the at least one of the matrix of analog push button assemblies when the at least one of the matrix of analog push button assemblies is pressed by a user's finger, into a corresponding digital-step-value;, a lighting arrangement including a plurality of light sources respectively associated with the matrix of analog push button assemblies in a manner so as to individually illuminate each of the matrix of analog push button assemblies; and, a processor which is coupled to the analog-to-digital converter and which is configured to control the lighting arrangement to light the plurality of light sources based on the digital-step-value such that a number of light sources among the plurality of light sources being lit is proportional to the corresponding digital-step-value.
