Abstract (en)
[origin: EP0190717A1] 1. A circuit arrangement (10) having a differentiating stage (14) for the control of a bistable relay (9) which has a monostable switching characteristic and which in the working position lies in series with a polarity-reversal capacitor (12), which for the switching-off of the relay (9) is dischargeable by way of this, in which respect the polarity-reversal capacitor (12) lies in the bridge diagonal of a bridge circuit which is connected to a direct-voltage supply circuit (8), characterized in that the bridge circuit has in its parallel branches on the one hand a series connection of the relay (9) with a relay switch (20) and on the other hand a series connection of a working switch (13) with a switch-off switch (15) working complementarily to this, and a control signal transmitter (11) connectd in parallel with the bridge circuit to the supply circuit (8) is provided, from which the working switch (13) or respectively the switch-off switch (15) are controllable and the relay switch (20) can be switched through transientally by way of the differentiating stage (14).
