<p>The device (1) has an adjustment mechanism (3) e.g. rotary potentiometer, comprising a rotary shaft (32) adjusting a parameter. A rotary knob (2) has a shank with a hollow bore (23) for accommodating the rotary shaft. A clamping ring (4) clamps the shank on the shaft. A stopper (5) prevents displacement of the clamping ring in an axial direction when sliding the knob onto the shaft. The clamping ring has a beveling (41) with center opposite to the shank. The stopper is a part of a housing front (6), where the mechanism is positioned behind the stopper.</p> |
