ABSTRACT:
An adjustable electromechanical device, such as a potentiometer, a variable capacitor or a multiple switch, comprising a shaft which is rotatably mounted in a sleeve. The shaft is retained in the axial direction by an annular wall portion of the bearing sleeve at the free end of the sleeve, the annular wall portion is spaced from the remainder of the sleeve by at least one but preferably two evenly distributed slots which extend circumferentially in the wall of the sleeve. The annular wall portion remains connnected to the remainder of the bearing sleeve at at least one location. The free parts of the annular portion are deformed to engage a circumferential groove in the shaft.
