It consists of an electronic board (7) with a microcontroller (17) which controls its opening/closing and communicates with an antenna (8) built into a knob block, made up of a knob (3) joined permanently to a push button/mounting hole piece (5) which has an upper surface (s), lateral slots/guides (13) and a fixed knob guide (4) carrying the antenna (8) and in which the knob (3) moves up and down under the action of a coaxial spring (11) on the knob guide (4) and pins (14) of a tongue block (6) sliding on the slots (13) causing movement in the tongue block. The microcontroller (17) operates a bi-stable solenoid (9).
