摘要

Improvements in combined switching and tuning devices for television receivers of two frequency ranges, characterized in that the geometrical arrangement of the bodies of the VHF channel selector and the UHF frequency tuner is carried out in order to obtain the best effect of its coupling with the least loss of energy, and because the kinematic transmission of the movement of rotation from the actuating elements to the respective tuning axes is carried out by means of a unified mechanism that makes it possible to carry out the sliding of the transmission cord of the movement, for the tuning axis in the ultra-high frequency range, on a coaxial drum, but independent, of the channel selector axis in the very high frequency range, the mechanism being completed by means of a pulley integral with the tuning axis of the aforementioned range.
