<p>This publication discloses a switching device combination for capacitive loads ( 3 ) connected to a direct voltage. The switching device combination includes an actual switch component ( 1 ) for connecting voltage to the capacitive load ( 3 ), a charging switch component ( 2 ) for connecting charging voltage to the capacitive load in the initial stage, which charging switch component is dimensioned for a lower current than the actual switch component ( 1 ), a controller component ( 4 ), by means of which the actual switch component ( 1 ) is controlled from an open state to a closed state and vice versa, with the aid of a mechanical lever ( 5 ), which is connected to a first shaft ( 6 ), and delay elements ( 11 ) for delaying the connection of the actual switch component ( 1 ), so that the closed charging switch component ( 2 ) will have time to charge the capacitive load ( 3 ) before the connection of the actual switch component ( 1 ). According to the invention, the controller component ( 4 ) includes a second shaft ( 7 ), which is operationally connected to the first shaft, in order to control the charging switch component ( 2 ).</p> |
