Abstract: An apparatus (1, 1a-c) to switch a light-emitting diode (2) or another load, comprising a mechanical switch (3), which comprises a moving electrode (4), wherein the moving electrode (4) is a contact, which electrically gets in connection with a further contact or electrode to enable a current flow while a closing phase and while an operation time and which moving electrode (4) can be separated from the further contact or electrode to interrupt current flow while a breaking phase of the mechanical switch (3), characterized in that the apparatus (1, 1a-c) comprises a solid-state-device (5), which is arranged in such a manner that current at least partially flows through the solid-state-device (5) while a closing or breaking phase and that current at least partially flows through the mechanical switch (3) in closed position while the operation time, achieves the object to drastically limit the arcing duration during the inrush current phase or switching on phase as well as during the breaking current phase or even to avoid any arcing.

Abstract: An arc chamber (10) for a DC circuit breaker comprises an entry side (E) adapted to receive an electric arc (50), which was generated outside of the arc chamber (10) and which propagates in a forward direction (F), a plurality of stacked splitter plates (11a ... 11f), and at least one inhibitor barrier (20a, 20b). The at least one inhibitor barrier (20a, 20b) is arranged on the entry side (E) to inhibit a reverse propagation of the electric arc (50) out of the arc chamber (10) in a reverse direction (R).
DC circuit breaker comprising an arc chamber. Use of an arc chamber with a circuit breaker in a DC electrical system.
