The device includes a PCB (200) connected to a power supply (400,500) and a removable module (100). The module includes an electronic circuit (101), contact pins (107,108) and a power supply pin (104). A connector (102) cooperates with contacts (304,305,306) placed on the pcb. Three bus lines (301,302,303) are provided for earth and power supply connections. The connection pins of the module have different lengths so that, when the module is plugged into the PCB, the pins are sequentially connected to their corresponding counterparts on the PCB. |
