US Patent 7965168 Fuse device with integrated switch

A fuse is provided that includes a housing and a first lead and a second lead. The fuse further includes a fuse element having a current capacity. The fuse element forms a part of an electrical pathway between the first lead and the second lead. The fuse also includes a switch unit in communication with the housing and in series with the fuse element. The switch unit has an open state and a closed state. When the switch unit is in the closed state, the electrical pathway is connected to form a closed pathway between the first lead and the second lead, and when the switch unit is in the open state, the electrical pathway is disconnected to provide an open circuit between the first lead and the second lead.
