A multi-tap device for tapping a main TV or rf signal to deliver attenuated signals to individual TV receivers includes a pair of socket assemblies for receiving input and output pins of a plug-in tap plate or printed circuit board carrying necessary attenuation/tap off circuitry. The socket assemblies connect the input pin to a main input cable for receiving the main rf signal and ac power, and connect the output pin to a main output cable or continuation of the main cable, for distributing the main rf signal(s) and ac power to cascaded down line multi-tap devices. A shunt printed circuit board is mounted between the socket assemblies, and has an rf/ac conductive strip for connection at either end to switches built into each socket assembly. As a tap plate is removed or unplugged from the socket assemblies, the switches operate to close before the input and output pins are electrically disconnected from sockets of the socket assemblies, for electrical connecting the input and output cables together to insure that the rf signals and ac power is continuously delivered to down line multi-tap devices without interruption.
