ABSTRACT:
A station-selecting device for a radio receiver comprises a rotatable control knob for driving an element of a tuning device which is capable of moving between two end positions. Motion transmission is carried out by applying a coefficient of friction between a shaft which is rigidly fixed to the control knob and a driven member. The coefficient of friction is of sufficiently high value to transmit motion when the moving element is located between its end positions and of sufficiently low value to cause displacement of the shaft in sliding motion against the previously driven member when the moving element reaches the end of travel. The driven member is a cyclindrical journal-bearing in which the shaft is rotatably mounted and which is preferably elastic, at least in the radial direction.
