Abstract
Abstract A control device which comprises a slidable shaft provided with a knob. The slidable shaft is gripped by two partitions in the knob, at least one of which is flexible in a plane transversely of the sliding direction of the sliding shaft. Relative displacement of the shaft and the knob is prevented by a fixing ridge in the knob which engages a detent groove in the sliding shaft.
