ABSTRACT:
A control device for an eddy current retarder having a plurality of energizing windings comprises an insulating support carrying a plurality of connecting terminals for connection to the retarder windings and a junction terminal for connection to one pole of a power supply. A plurality of contactors are provided for controlling the energizing of the retarder windings, each contactor corresponding to a connecting terminal and comprising first and second fixed contact members, a bridge contact co-operating with the first and second fixed contact members, and a pull-on contactor winding controlling the bridge contact. A first contact plate connects the first contact member of each contactor to the corresponding connecting terminal and a second common contact plate connects the second contact members of the contactors to the junction terminal. Each contactor winding is connected to a respective control terminal which is connected to a control selector for consecutively energizing the control terminals. The insulating support has a raised platform disposed between two oppositely directed flanges which extend parallel to the platform and are downwardly offset therefrom. The contactor windings are topped by their bridge contacts and are carried on the flanges, while the fixed contact members of the contactors and the contact elements are mounted directly on the platform.
