First and second contactors are arranged within a common housing 20 and their contacts are closable by respective electromagnetic means each comprising a fixed core 1, coil 3 and armature 2 acting on bridges 10 carrying movable contacts 18a. Fixed contacts are carried on a common U-shaped support 11 provided with common terminal 12, and other fixed contacts 18 are carried on supports 13 with terminals 12A, 12B. A mechanical interlock, provided by the interengaging ends of the movable contact carrying sleeves 4 attached to electromagnet armatures 2, prevents simultaneous closure of both sets of contacts. Each electromagnetic means may act on a group of such contacts. <IMAGE> |
