Claim:
1. A control switch comprising: a key, a housing structure, in an upper portion of which said key is secured in a manner such that said key is rotatable about a first fulcrum; a tip, secured at one end to the key and moving integrally with the key, so as to slide along a first axis of said key, countered by an elastic element; a printed circuit board, comprising at least two push-buttons, arranged in a lower portion of said housing structure; each push-button comprising at least one silicone dome and at least one electrical contact adapted to close an electrical circuit upon compression of said silicone dome; said housing structure comprising in an internal portion, a flared structure comprising two inclined contact planes symmetrically aligned with respect to a vertical axis and forming a first obtuse angle, on which said tip is slidable; said flared structure is structurally secured to the housing structure; at least one actuator positioned alongside said flared structure to be intercepted by the tip and causing electrical change of at least one push-button of said at least two push-buttons; each actuator is monolithic and comprises two contact portions, each of the contact portions located alongside an inclined contact plane, upon which the tip acts, and two actuation portions, each of the actuation portions located in proximity to a push-button and for acting upon a respective push-button exercising a force on a corresponding silicone dome; said contact portions are interposed between the two actuation portions; each actuation portion of the actuator lies on top of a respective silicone dome, so that said actuator only weighs upon the respective silicone dome; and wherein, depending on an action directly exerted by the tip on one of said contact portions, a corresponding actuator can rotate about one of two axes of rotation; each one of said two axes of rotation is respectively located on an actuation portion of the actuator; depending on a direction of rotation of the key, an axis of rotation of said two axes of rotation is located at an actuation portion opposite to an actuation portion that acts upon at least one of said at least two push-buttons.
