A contact arrangement is described for connecting a power supply to electrical components in a vehicle. The contact arrangement may include a first mechanical contact for connecting a first lead of the power supply to an electrical component, and a second mechanical contact for connecting a second lead of a power supply to the electrical component. The first and second mechanical contacts are configured to disconnect the power supply in the event of a collision. The first mechanical contact is configured to be arranged substantially perpendicular to the second mechanical contact in relation to a transverse plane of the vehicle.
