(EP956220-A1)      A switch arrangement for vehicle electrical control device including a conductor rail (50) with given thermal conductivity and thermal capacity and connected to a first given current supply potential, a number of switch devices (101-401) for switching at least one associated current load (1-4c) of the respective switch device on and off. In each case, a first line (current) terminal of the switch device (101-401) is connected to the conductor rail (50) with given thermal conductivity and thermal capacity.    Each current load (consumer) (1-4c) of a respective switch device (101-401) is connected into circuit between a second line (current) terminal of the switch device (101-401) and a second assigned current supply potential. The first given current supply potential is specifically the battery 'positive' and the second the battery 'negative' i. e the 'earth' potential.    USE -   For implementing in motor vehicle electrical systems-control devices.    ADVANTAGE -   Has good switching and monitoring properties, effective removal of heat and is cost-competitive.
