Abstract
A control device suitable for use in a vehicle includes a circuit board and a thermal fuse holder including a removable spacer element and a plurality of breaker elements. The thermal fuse holder is attached at a terminal structure and, when the terminal structure is attached to the circuit board, the breaker elements engage the removable spacer element to hold the breaker elements at the circuit board. After terminals of the terminal structure and the breaker elements are soldered at the circuit board, the removable spacer element is removed from the thermal fuse holder, whereby the breaker elements are held at the circuit board via solder joints and are biased away from the circuit board. When the temperature at a respective solder joint exceeds a threshold temperature that melts the solder, the respective breaker element moves away from the circuit board to break the electrical connection at the solder joint.
