A control system for a component of a rescue hoist attached to an aircraft is disclosed. In various embodiments, the control system includes a first bus extending between a control module of the rescue hoist and a control input device; a second bus extending between the control module of the rescue hoist and the control input device; and a hardwire extending between the control module of the rescue hoist and the control input device.

To achieve a size reduction by on-off controlling non-contact switching devices with a microcomputer. When a three-phase alternating-current electric motor is to be used, lead wires of the three-phase alternating-current electric motor are connected to output terminals of a control board. When a single-phase alternating-current electric motor is to be used, two supply terminals of the control board are electrically connected together through a first connecting member, and one end of the first connecting member is defined as a single-phase alternating-current power supply terminal. A second connecting member is connected to a supply terminal, and one end of the second connecting member is defined as a single-phase alternating-current power supply terminal. A main winding of the single-phase alternating-current electric motor is connected to the output terminals, and an auxiliary winding is connected to the output terminal and the second connecting member.
