A rotary switch for providing deicing power to the heaters of a helicopter rotor includes a conductive rotor with conductive protrusions located thereon. Conductive fingers are arranged such that a pair of conductive fingers are in electrical communication with a pair of conductive protrusions for a given position of the conductive rotor. The pair of conductive fingers are in electrical communication with the heaters of a helicopter rotor such that if one the pair of electrical fingers fails to make electrical contact with its respective conductive protrusion electrical power is still delivered to the heater.
