Patent ID: 7315005

Claim:
Control panel of the touch-switch or sensor-switch type comprising: an external control board ( 1 ) provided with at least partly transparent surface portions ( 2 ), means for illuminating said transparent surface portions from the inside, capacitive-type detecting or sensing means provided on the backside of said control board and adapted to detect the presence, on the front side of the control board, of bodies that modify the electric field containing said detecting means, wherein said means for illuminating comprise: a plurality of illumination channels ( 7 ) comprised laterally between pairs of opaque septum-like partitions ( 8 , 9 ) that are arranged in substantially parallel manner relative to each other and substantially orthogonal to said control board ( 1 ), and located in the space on the backside of said control board, and in that said capacitive-type detecting or sensing means comprise conductive elements ( 10 , 11 ) applied substantially either on the mutually facing surfaces of contiguous septum-like partitions ( 8 , 9 ) or on one of said surfaces and a ground not comprised between said septum-like partitions ( 8 , 9 ), in contact thereto.
