Abstract
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.

A fuse, comprising:
- a housing;
- a first lead and a second lead;
- a fuse element having a current capacity and forming a part of an electrical pathway between the first lead and the second lead;
- and
- a switch unit in communication with the housing and in series with the fuse element, the switch unit having an open state and a closed state, wherein 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,
- wherein the switch unit includes a contacting portion that communicates with the fuse element when the switch is in the closed state.

A switch for a fuse, comprising:
- a moveable portion to select between an open circuit state and a closed circuit state;
- a housing surrounding the moveable portion at an outer periphery and integrated into a fuse housing;
- and
- a contacting portion controlled by the moveable portion and placed in communication with a fuse element thereby making a closed pathway between fuse leads when the closed circuit state is selected,
- wherein the moveable portion is provided on an upper surface of the fuse.
