The invention concerns electronic keyboards, in particular those used in dark surroundings and which therefore require that the keys are illuminated. The keyboard comprises a rigid printed circuit (10) whereon are soldered switches (20) capable of being indirectly actuated by the user's finger, each switch being topped with a key (30) at least partly transparent and illuminating means being provided for lighting up the key from the rear. The invention is characterised in that a pliable printed circuit (50), bearing conductors powering the electroluminescent diodes, is interposed between the keys (30) and the rigid printed circuit (10) bearing the switches; the pliable printed circuit comprises a rigid part (54) between a key and the corresponding switch, and the electroluminescent diode (60) which is to illuminate each key from the rear is soldered on the pliable printed circuit rigid part, between the key and the switch. The key preferably comprises a cavity wherein is housed the diode. The key presses on the switch via the rigid part (54) without pressing on the diode.
