Improved pushbutton, characterized essentially by the fact that it consists of a pushbutton consisting of a cylinder inside which a bulb is mounted and the visible base covered by a transparent glass or plastic and the pushbutton mounted on a fixed spring to a piece supports, being the central contact of the bulb and the side of it, establishing contact on an insulating plate that has a deployable central contact and a fixed circular contact, this insulating plate being on a spring, and that when pressing the push button and lowering the insulating plate by sliding inside an insulating support piece, contact is made with the terminals of a transformer fixed to said piece, closing the circuit and lighting the bulb, closing and opening other circuits at the same time.
