Switch-off device for a record changer or automatic record player having a switch pin within the tone arm rest arranged to be depressed by the tone arm and a mechanism which pivots the tone arm between an inoperative position and operative positions. When the tone arm is lowered onto the arm rest the switch pin operates control members which release a switch control locked in the switch-on position only after the mechanism has been returned to the inoperative position by the driving motor.
