Patentansprüche:Patent claims:1. Stromrichtungsrelais, dadurch gekennzeichnet, daß das Stromrichtungsrelais nach
dem Ausschlagen in einer Richtung bei sich umkehrender Stromrichtung am Ausschlagen
nach der anderen Seite mechanisch verhindert ist.1. current direction relay, characterized in that the current direction relay according to
the deflection in one direction when the current direction is reversed at the deflection
is mechanically prevented on the other side.2. Stromrichtungsrelais nach Anspruch 1,
dadurch gekennzeichnet, daß eine am Stromrichtungsrelais vorhandene Sperreinrichtung
in einen Zahnkranz mit schrägen Zähnen eingreift.2. converter relay according to claim 1,
characterized in that a blocking device present on the converter relay
engages in a ring gear with oblique teeth.3. Stromrichtungsrelais nach Anspruch 1,
dadurch gekennzeichnet, daß die Sperrung des Stromrichtungsrelais bei Betätigung in
der einen Richtung an einer Weiche vorbeistreift, die ein Rückbewegen bei sich umkehrender
Strornrichtung verhindert.3. converter relay according to claim 1,
characterized in that the blocking of the current direction relay when actuated in
the one direction passes a switch that moves back when turning
