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. |

1. A control device (1), including:
a rotary switch (2) having a body (6) and a control rod (20) which extends along an axis (A), said control rod (20) having a general cylindrical form, and being mounted with at least one degree of rotational freedom in relation to the body (6) along the axis (A), said control rod (20) being provided with at least one diametrical slot (21) which extends in a plane of reference (P) defined by a first diametrical direction (X) and the axis (A), said diametrical slot (21) thus defining the first and second half-parts (20a, 20b) of the rod, a molded plastic knob (3) which includes a housing which is adapted to receive said control rod (20), said housing including at least two flexible fingers (31, 32) which are diametrically opposed and resiliently provided in order to press the two half-parts (20a, 20b) of the rod radially inward, and at least two fixed fingers (33, 34) which are diametrically opposed and connected together by means of a connecting wall (35) which extends along the plane (P),the connecting wall (35) being received in the diametrical slot (21) without any substantial play in order to immobilize the knob (3) in relation to the control rod (20) in a direction (Y) perpendicular to the plane of reference (P), the two flexible fingers (31, 32) holding the knob (3) along the axis (A) by means of friction or by means of mechanical or spring-assisted blocking. |
