ABSTRACT:
A toothed wheel is fixed to the control shaft of a television channel selector. A second class lever is mounted to freely rotate about a fulcrum colinear with the axis of the control shaft. A remotely operable cord is attached to the lever at an end thereof opposite the fulcrum to rotate the lever about the fulcrum. A pawl is mounted on the lever and has a hook end which engages the teeth of the toothed wheel. When the lever rotates, the pawl rotates the toothed wheel and thus the control shaft.
