ABSTRACT: A device in an automatic record player or re- cord changer for the combined adjustment of the turn- table speed and the lowering position of the pick-up arm onto the edge of a record which is placed on the turntable so as to be played, the lowering position of the pick-up arm being dictated by engagement with a lever step of a two-armed shift lever which is pivotable about a ho- rizontal spindle, which step has been selected by a sensing means, in which device the free end of a single- ar, dead-centre lever engages with the shift lever at one of two possible speed settings with the aid of a dead-centre spring, whilst during pivoting of the shift lever, in order to bring a lever step for an other drop- ping diameter (17 cm) into the path of the pick-up arm, the free end is pivoted beyond the dead centre by said lever and swings against the switch which changes the speed.
