Control panel of the touch-switch comprising: an external control board with transparent surface portions, devices for illuminating the transparent surface portions from the inside, capacitive-type detecting or sensing devices on the backside of the control board and adapted to detect the presence, on the front side of the control board. The devices for illuminating comprise a plurality of illumination channels comprised laterally between pairs of opaque septum-like partitions arranged in parallel manner on the backside of the control board. The capacitive-type detecting devices comprise conductive elements applied either on the mutually facing surfaces of contiguous septum-like partitions or on one of the surfaces and a ground not comprised between the septum-like partitions. The illuminating channels are delimited on the front side by the external control board at the transparent surface portions and, on the back side, by support members arranged at the rear side of the septum-like partitions.
