ABSTRACT:
A mechanical channel selector device for the remote switching of channels of a television receiver includes a switching mechanism coaxially mounted to the television receiver channel shaft and operatively connected to a manual control mechanism. The switching mechanism includes a switching disc having a series of notches corresponding to the television channels on the inside surface which cooperate with a pawl member pivotally mounted to a switching actuator lever coaxially mounted on the disc and operatively connected to the control mechanism. The control mechanism includes a spring biased control knob movable between an at rest position and an actuated position. Movement of the control knob results in the pivotal movement of the actuator lever and the pawl member engaging a notch on the switching disk to rotate the television receiver channel shaft to the next channel.
