ABSTRACT:
A control mechanism for automatically raising, swinging and lowering the pickup arm of a record player in response to the positioning of a finger of a user. The user's finger will selectively bridge pairs of contacts to establish an electrical circuit and generate an input signal to logic circuitry. The logic circuitry provides control signals which, through suitable transducers, control the motion of the arm.
