ABSTRACT:
A television receiver is provided with two or more input terminals for receiving respective RF input signals from an antenna and an auxiliary device, such as a personal computer or a video game, and a terminal selector for selecting one of the input terminals. The antenna may receive a plurality of broadcast signals having different frequencies characteristic of respective channels and, for selecting either one of such broadcast signals received at a first input terminal or the auxiliary signal received at a second input terminal and which also has a characteristic frequency, the television receiver has a plurality of manually actuable channel selecting switches and a manually actuable terminal selecting switch mounted on the cabinet of the receiver, and the receiver is tuned for the signal frequency corresponding to the actuated switch. An interlock arrangement insures that only one switch at a time is actuated and enables the operator to select a channel or the auxiliary device in a single actuation. The actuation of the terminal selecting switch is readily indicated to avoid inadvertent actuation thereof. Further, the terminal selector may include a coupling member which, when the terminal selecting switch is actuated to select the second input terminal, actuates a tuning control switch for effecting tuning of the receiver to the signal applied at that selected input terminal.
