Abstract
Abstract A rotary switch for coupling coaxial transmission lines which are connected to ports of the switch has a rotor for interconnecting any two adjacent ports by connecting the center conductors of the adjacent ports. The rotor is actuated by two electrical drives which drive the rotor in opposite directions, each to a predetermined position when the electrical drive is energized. Each electrical drive actuates a different set of micro-switches, one switch in each set controlling electrical power to the other electrical drive so that the drives are energized at different intervals and another switch in each set providing logic signals for turning transmitters on and off.
