  • AM/FM band selector
    Patent number: 5020145
    Abstract: An AM/FM band selector is provided for selecting AM and FM bands by a single band switch. By using only a single band switch, power consuming parts are eliminated so that power consumption of the selector is reduced. Also, impulse noise which occurs when selecting bands and switching on and off the power source is removed to provide an efficiently operating AM/FM band selector. The AM/FM band selector having a single band switch prevents simultaneous selection of AM and FM bands.
