Abstract

See full text

A switch device for a turntable with a starting device which closes the switch for the drive motor on the one hand by means of a swinging movement of the pick-up arm manually during swinging-in from its support bracket onto the record, and on the other hand by means of a direct current dc low voltage solenoid which is actuated by momentary actuation of an operating service element, the latter being connected with a first contact pair, and a switch-off device which acts automatically with the arriving of the pick-up or reproducing head in the run-out groove of the record, the switch-off device opening the switch for the drive motor and containing a switch for the entire current supply of the device from the power supply mains. In a per se known manner a common main switch lies in the circuit for the drive motor and the other current supply of the device, and a second contact pair is connected with the operating element for starting the device such that it opens and closes in the same direction with said first contact pair for the solenoid and is connected parallel to the main switch.
