Abstract

A channel selector for a television receiver, comprising a plurality of channel selection switches and a group of tuning potentiometers, each channel selection switch being associated with one of the tuning potentiometers of the group in order to make possible the connection of this tuning potentiometer between a voltage source and a capacitive diode for tuning purposes, characterized in that two groups of tuning potentiometers are provided, each potentiometer of the second group being also associated with one of the channel selection switches, having also provided a group selection switch, whereby the potentiometers of the first or second group can be inserted, as desired.
