Voltage supply device for remote control unit e.g. for motor vehicle doors and valves, includes connecting device connected into circuit between an electrical blocking state and an electrical conducting state

摘要

A voltage supply unit to at least a first load (3) and a second load (4), has a first expendable voltage source (battery) (1) for first load (3) and second expendable voltage source (battery) (2) for second load. A connecting device (30) can be connected into circuit between an electrical blocking state and an electrical conducting state, where each of two terminals of the connecting device (30) is joined to the first and to the second batteries, such that the batteries (1,2) are connected in parallel in the conducting state of the connecting device (30). An Independent claim is included for a portable remote control unit.
