1. Schaltungsanordnung zur Unterdrückung eines Lichtbogens bei einem Schaft­ kontakt (1, 1', 1"), mittels welchem ein eine Wechsel-Versorgungsspannung (4, 4', 4") und eine Last (3, 3', 3") aufweisender Laststromkreis schließbar ist, mit einem zum Schaltkontakt (1, 1', 1") parallel geschalteten elektronischen Schalter (2, 2', 2"), dadurch gekennzeichnet, daß der elektronische Schalter (2, 2', 2") ein Triac ist, dessen Steuereingang (2c, 2c', 2c") mit einem Abgriff (5, 5', 5") des Laststromkreises verbunden ist, an dem die Wechsel-Versorgungsspannung (4, 4', 4") bei geschlossenem Schaltkontakt (1, 1', 1") ein Potential erreicht, bei welchem der Triac (2, 2', 2") zündet.1. Circuit arrangement for suppressing an arc in a shaft contact ( 1 , 1 ', 1 "), by means of which an alternating supply voltage ( 4 , 4 ', 4 ") and a load ( 3 , 3 ', 3 ") Load circuit can be closed with an electronic switch ( 2 , 2 ', 2 ") connected in parallel with the switch contact ( 1 , 1 ', 1 "), characterized in that the electronic switch ( 2 , 2 ', 2 ") is a triac , whose control input ( 2 c, 2 c ', 2 c ") is connected to a tap ( 5 , 5 ', 5 ") of the load circuit at which the AC supply voltage ( 4 , 4 ', 4 ") is closed when the switch contact is closed ( 1 , 1 ', 1 ") reaches a potential at which the triac ( 2 , 2 ', 2 ") ignites. 2. Schaltungsanordnung nach Anspruch 1, dadurch gekennzeichnet, daß zwischen der ersten Anode (2b, 2b', 2b") und dem Steuereingang (2c, 2c', 2c") des Triacs (2, 2', 2") ein im Laststromkreis liegender Widerstand (3, 7', 7") angeord­ net ist. 2. Circuit arrangement according to claim 1, characterized in that between the first anode ( 2 b, 2 b ', 2 b ") and the control input ( 2 c, 2 c', 2 c") of the triac ( 2 , 2 ', 2 ") a resistor in the load circuit ( 3 , 7 ', 7 ") is net angeord. 3. Schaltungsanordnung nach Anspruch 2, dadurch gekennzeichnet, daß der Widerstand (3) zumindest Teil der Last (3) ist.3. Circuit arrangement according to claim 2, characterized in that the resistor ( 3 ) is at least part of the load ( 3 ). 4. Schaltungsanordnung nach Anspruch 2, dadurch gekennzeichnet, daß der Widerstand (7', 7") ein separater Referenzwiderstand ist.4. Circuit arrangement according to claim 2, characterized in that the resistor ( 7 ', 7 ") is a separate reference resistor. 5. Schaltungsanordnung nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß der Steuereingang (2c") des Triacs (2") über einen Transformator (8") mit dem Abgriff (5") des Laststromkreises verbunden ist.5. Circuit arrangement according to one of claims 1 to 4, characterized in that the control input ( 2 c ") of the triac ( 2 ") is connected via a transformer ( 8 ") to the tap ( 5 ") of the load circuit.
