A switch (1) for roof lights (2) has: a supporting frame (3); a push-button (7) slidably mounted on the frame (3); a printed circuit, which is associated to the frame (3) and defines two operative positions for a lamp-bulb; and an actuator (13), which is set between the push-button (7) and the printed circuit (8) and is moved by the push-button (7) between the two operative positions; the actuator (13) being provided with a rolling element (18), which can roll on the printed circuit (8) between the two operative positions, and an motion-imparting arm (15), which supports the rolling element (18) and is actuated by the push-button (7) for moving the rolling element (18) itself between the operative positions.
