Device including a fuse

A fuse comprising:

• a first printed circuit board including a first electrical via and a second electrical via;
• a conductor electrically connected to the first electrical via and the second electrical via, the conductor configured to conduct an electrical current;
• and
• a member positioned between a second printed circuit board and the conductor;
• wherein the conductor is bonded to the first printed circuit board by a bonding material;
• wherein the bonding material is configured to deteriorate when a temperature of the first printed circuit board exceeds a threshold value, and
• wherein, in response to the bonding material deteriorating, the member moves the conductor away from the first printed circuit board to prevent conduction of the electrical current.

A device including a conductive path for passing electric current, the device comprising:

• a terminal;
• and
• a spring fuse connected in the conductive path and electrically connected to the terminal, the spring fuse including:
• a fixed base,
• an extension spring connected to the fixed base at a first end,
• a power path connection connected to the extension spring at a second end,
• a first conductive pad positioned perpendicular to the power path connection,
• a second conductive pad positioned parallel to the first conductive pad,
• a first solder joint connected to the first conductive pad,
• a second solder joint connected to the second conductive pad;
• wherein the first solder joint or the second solder joint are configured to melt when a respective temperature of the first solder joint or the second solder joint exceeds a threshold value, and
• wherein the power path connection is configured to retract toward the fixed base when the first solder joint and the second solder joint melt.
