CONTROL DEVICE FOR A VEHICLE
First Claim
1. A control device suitable for use in a vehicle, said control device comprising:
- an electrically conductive element having a first end in electrical connection with a first solder joint and a second end in electrical connection with a second solder joint;
wherein a center region of said electrically conductive element is in electrical connection with a vehicle power source; and
wherein, when a temperature at said first solder joint exceeds a threshold temperature and a temperature at said second solder joint is below the threshold temperature, electrical connection at said first solder joint is broken and electrical connection at said second solder joint is not broken.

Abstract
A control device suitable for use in a vehicle (such as, for example, for a glow plug of a vehicle) includes an electrically conductive element having a first end in electrical connection with a first solder joint and a second end in electrical connection with a second solder joint. A center region of the electrically conductive element is in electrical connection with a vehicle power source. When a temperature at the first solder joint exceeds a threshold temperature and a temperature at the second solder joint is below the threshold temperature, electrical connection at the first solder joint is broken and electrical connection at the second solder joint is not broken.
