Abstract
The invention concerns a control assembly, in particular for motor vehicle steering column top portion (1), comprising several switching modules (7; 9; 13; 15) and a microcontroller (19) mounted on a motherboard (17) for interpreting a switching state based on the identifier of the module to deliver an appropriate control signal, the motherboard (17) having several connecting locations (E1, E2, E3, E4), and each module (7; 9; 13; 15) having an identical number N of predetermined tracks (L1, L2, L3, L4, L5, ID1, ID2; CS1; CS2; CS3; CS4) to be connected to tracks associated with the motherboard (17). The corresponding exit tracks (L1, L2, L3, L4, L5, ID1, ID2) of each switching module (7; 9; 13; 15) are interconnected and connected together on the same input of the microcontroller (19), and the control assembly comprises for each location (E1, E2, E3, E4) means for activating reading of a switching state of a module connected at said location, said activating means being monitored by the microcontroller (19).
