US Patent 9475459 Self-powered wireless fuse switch

A self-powered wireless fuse switch is disclosed that is a plug-in replacement for a fuse found in the electrical system of vehicles. The self-powered wireless fuse adds remote-controlled switching capabilities for short and long-range control of power to subsystems of a vehicle electrical system. The wireless fuse switch includes an internal transceiver that receives commands from a remote control unit and controls the position of an internal relay. The wireless control module interfaces with a fuse socket of the vehicle to selectively allow or interrupt power from the vehicle to the subsystem of the vehicle electrical system. The wireless fuse switch includes either a two-blade or three-blade harness assembly that allows the wireless fuse switch to be received within the fuse socket of the vehicle.
