Abstract

A manual radio selector switch, normally used in aircraft, is provided with a particular switch position which is connected to a cyclical stepping switch. When the manual radio selector switch is in this position, the choice of radio is effected by the cyclical stepping switch. The cyclical stepping switch is stepped under control of the pilot who changes from one radio to the next by actuating a stepping switch on his control stick, whereby, when the manual radio selector switch is in the particular switch position, the pilot can change radios without the necessity of removing his hand from the control stick. One of several indicator lamps on the instrument panel indicates which radio has been selected by the pilot. When the pilot is transmitting, the light corresponding to the radio being used will flash.
