Abstract
A control mechanism for raising, swinging and lowering the pick-up arm of a record player comprising a disc having an arcuately shaped depression in the periphery thereof. The contacts of an electrical contact sensor switch are located in the disc peripheral depression and bridging of these contacts will cause generation of a first command signal for the control mechanism. Devices for generating second and possibly third command signals are associated with the disc which may be rotatably mounted.
