ABSTRACT:
A push button VHF television tuner includes a fixedly mounted core, which is a conventional tuner turret cylindrical core having an elongated contact strip for each channel connected to reactive components on switch wafers within the turret. Plungers are arrayed around the circular periphery of the core along each contact element and longitudinally spaced contact rings encircle the core turret and plungers at the location of each contact position on the strips. The plungers carry radially directed contact fingers for bridging between the rings and contacts on the strips upon plunger depression. The loops feed the radio frequency receiving circuitry.
