Abstract
(EN)

In a device for suppressing voltage drops in apparatuses which can be connected with a battery via at least two lines, one line serves to supply voltage permanently and the other line can be switched on or off via a switch. To prevent voltage drops which can occur on the permanent voltage supply side from negatively affecting the voltage supply to the apparatus, the permanent voltage supply is taken over by the other connected line via a circuit arrangement situated between the two lines when voltage drops occur while the switch is closed.
