Abstract (en)
[origin: EP0887814A2] The control circuit has a pair of electrical windings (L1,L2) which are each connected in series with a respective semiconductor switch (S1,S2) connected in parallel with closure of one or other switch for switching the magnetic actuator between its stable positions. A further parallel arm with a free-running diode (D) and a cancellation resistance (R) is connected in parallel with the electrical windings, all 3 parallel arms connected in series with a discharge switch (So) for an energy store (E).
