Abstract: An electrical connection is made between an appliance and a power cord by means of a rotatable plug which is bonded to one end of the power cord and rotatably connected to a socket in the appliance. The plug effects electrical contact with the socket through a central contact member and an exposed concentric contact member which is coaxially disposed relative to the central contact member. The central contact member and the concentric contact member are engaged by spring contacts in the socket which allow the plug to rotate while always maintaining electrical contact. In order to isolate the electrical connection between the appliance and the plug from axial and transverse stresses, the plug is provided with a strain relief bushing which transfers stresses between the cord and appliance to the housing of the appliance. The bushing also allows the plug to rotate or swivel relative to the housing so that torsional stresses applied to the cord are kept to a minimum.
