Abstract
The invention relates to a switching device for motor vehicle column top comprising a microcontroller (1). The latter comprises at least two distinct functional switching blocks (3, 5), each block being linked to two signal inputs (e1, e2, e3, e4) and two signal outputs (a, b, c) of the microcontroller (1), a signal output (a, b, c) or a signal input (e1, e2, e3, e4) of which is linked solely to a single functional block (3, 5) and comprising four switches (7, 9, 11, 13, 15, 17, 19, 21), each switch (7, 9, 11, 13, 15, 17, 19, 21) being linked to a signal input/output pair of the microcontroller (1) distinct from that of the other three of the same block (3, 5). At least two distinct functional switching blocks (3, 5) share only either one signal output (a, b, c), or input (e1, e2, e3, e4) of the microcontroller (1), and the microcontroller (1) is configured so as to deduce front a signal dispatched by at least one signal output (a, b, c) that has passed through at least one functional switching block (3, 5) and has been received at at least one signal input (e1, e2, e3, e4), the state of switching of at least one switch (7, 9, 11, 13, 15, 17, 19, 21) of a functional switching block (3, 5).
