<p>The present invention relates to a composable modular push button, preferably used on control panels for military-type applications, having a light source and a control system thereof. The invention uses a novel technique for controlling the parameters characterizing the LED devices, in particular the possibility of varying the luminous intensity against a voltage sweep, commonly defined as "dimming" in the illuminotechnical field, though keeping constant over time the current delivered by the circuit and the operating temperature, compatibly with what is stated by MIL standards.</p> |
