A control device, includes a switch (2) with a rotary control rod (20) having a diametrical slot (21) which extends in a plane of reference (P), a molded plastic knob (3) which includes a housing receiving the control rod, the housing including two flexible fingers (31, 32) which are diametrically opposed and provided so as to be resilient radially inward, and two fixed fingers (33, 34) which are diametrically opposed and are connected together via a connecting wall (35) which extends along the plane (P), the connecting wall (35) being received in the diametric slot without any play in order to immobilize the knob in relation to the control rod in a direction (Y) perpendicular to the plane (P), the two flexible fingers holding the knob along the axis (A) by friction or by mechanical or spring-assisted blocking. |
