Automatic switch-off mechanism for a single play record player having a manually operated dash pot type cue-in device for the pick-up arm, trip mechanism which is operated by the movement of the pick-up arm when the stylus enters the "run-out" groove of a record so that the trip mechanism moves a switch-off device to effect the switch-off sequence and a locking device to hold the trip mechanism in a locked position in which it cannot operate, the locking device being coupled to the manually operable member which operates the cue-in device so that the locking device is released from the trip mechanism only when the cue-in device is operated to allow the pick-up arm to descend.
