Abstract
A frequency band selection switch and variable resistor assembly for one channel of a television tuner in which tuning is performed by varying a tuning voltage. A tuning shaft is connected to the slider of the variable resistor through a harmonic drive reduction gear assembly. A tuning scale is connected to the slider through a bored tuning scale shaft through which the tuning shaft coaxially extends. A bored switch shaft through which both the tuning and tuning scale shafts coaxially extend carries a movable contact of the band selection switch and a frequency band indicator. An assembly support member has a graduated dial associated with both the tuning scale and the frequency band indicator in a unitary manner.
