ABSTRACT:
An operator-controllable detent mechanism is provided for a combination VHF-UHF television tuner. Separate torsionally-loaded detent springs are provided for two detent wheels which are mounted on the common station selector shaft of the tuner. A manually-operable control member concentric with the selector shaft is employed selectively to remove the torsional load on one detent member or the other so that the common selector shaft may be detented for combined VHF-UHF reception, VHF only reception or UHF only reception.
