Zusammenfassung:	A propeller assembly is provided including a plurality of blades (22) arranged in diametrically opposed pairs. Each of the plurality of blades (22) has an electrical deicer (26) located thereon. The propeller assembly also includes a slip ring (40), and a stationary brush (52) arranged in contact with the slip ring (40). The brush (52) is configured to transfer electrical power from a power source to the slip ring (40). A movable portion (135) of an actuator (130) is configured to sequentially couple the electrical deicers (26) of each pair of blades (22) to the rotating slip ring (40).
