Abstract:
An electric circuit comprising an electrically activatable first relay (21) which connects a first connecting point (1) electrically to a second connecting point (2) in a non-activated state and connects the first connecting point (1) to a third connecting point (3) in an activated state,and a second electrically activatable relay (22) which connects a first connecting point (1a) electrically to a second connecting point (2a) in a non-activated state and connects the first connecting point (1a) to a third connecting point (3a) in an activated state, an inductive load, preferably one or more electric motors (14), being coupled between the two first connecting points (1) and (1a) so that the inductive load is connected to a power supply (12) in given positions of the relays (2, 3a; 3, 2a), said circuit being adapted to activate both relays (21, 22) when the voltage drop across the inductive load is to be interrupted or inverted.
