Abstract
A radio keyboard supports a potentiometer on its rear surface and a popout control in the front surface. The control includes a housing between the keyboard and the radio trim plate, inner and outer stationary cams, and a rotatable cam follower on a shaft which controls the potentiometer. The cams index the cam follower each time a knob on the shaft outer end is depressed. The cams alternately hold the follower and the shaft in retracted and extended position.
