摘要
A protected reversing contactor is disclosed comprising two electromagnets intended to be alternately energized and whose armatures actuate two sets of respective phase switches and two acknowledgement switches mounted respectively in series in the supply circuit of the two coils of the two electromagnets. These two acknowledgement switches are actuated by a transmission system comprising two coaxial rotary shafts disposed end to end and each having an arm adapted to be driven in rotation, in one direction, by one of the electromagnets and a finger cooperating with the acknowledgement switch of the other electromagnet.
