Abstract: An electronics arrangement has at least one ventilator and at least one essentially flat support structure which is fitted with one or more electronic components and which is provided with one or more cooling ribs. A cooling air passage passing through the flat support structure is configured therein. The ventilator and the cooling air passage are configured and arranged in such a way that the ventilator produces a cooling air stream, so that the cooling air first passes along one side of the support structure, in a function whereby at least one component and/or a cooling rib are cooled, then passes through the cooling air passage and subsequently, flows along the other side of the support structure in a function whereby at least one electronic component and/or a cooling rib are cooled. This enables efficient cooling of the electronic components of the electronic arrangements.

Abstract: A switching process and apparatus for switching-off an electric energy supply of a vehicle has two switching elements which are mounted in the proximity of the electric energy source, and couple it to supply electric energy to consuming devices of the vehicle. In the event of a fault, an all-pole switch-off is implemented by opening both switching elements. One of the two switching elements is an operating switch by means of which the electric energy source can be switched off in normal operation. In the case of a vehicle driven by an electric motor in a normal operation the driving current of the electric motor is first controlled downward, and the operating switch is then opened when the driving current is decreased.
