  • Patent number: 5027399
    Abstract: Apparatus is provided for switching traps in and out of a cable television signal path. A plurality of double pole double throw switches is connected in series with the signal path. Each switch has a first actuated position, a second actuated position, and an off position. The switches connect corresponding traps to the signal path in the first actuated positions. In the second actuated positions, the switches provide a through connection in series with the signal path. An open circuit is provided along the signal path when a switch is in the off postion. Actuation and disconnect signals transmitted over the cable television network selectively actuate the switches to the frist, second, or off positions. The switches are constructed of solid-state components such as diodes, and are actuated by unipolar biasing signals.
