A television switch module for switching output lines of television high frequency signals, comprising: first and second input lines for respectively inputting television high frequency signals; first and second amplifiers for respectively amplifying input signals; first and second output lines for outputting the signals after amplified; a branching unit for branching an input signal; a relay switch for switching the signal lines; a relay switch control means for operation to switch the relay switch; and a power supply control means for controlling power supply to the respective amplifiers, and for stopping the power supply to an amplifier inserted in an unused input line. This makes it possible to operate only a necessary amplifier, and to reduce power consumption.
