ABSTRACT:
An electrical circuit plug for insertion into a current type socket without breaking the circuit normally connected through the socket contacts. When the plug is inserted into the socket, the plug terminals are connected in series with the output line connected to the socket and a manually variable resistor is connected to the plug terminals. The resistor is then varied to control the volume of a local transducer from a remote location. One of the plug contacts is a resilient conductor which makes electrical connection to one side of the output line.
