摘要： The parts of the three-pole contactor (FIGS. 1 and 2) are designed so as to enable economical assembly thereof without any screws or similar fasteners. A molded contact carrier (12) having windows (12a-c) that retain movable bridging contacts (14, 16, 18) and their bias springs (20, 22, 24) and armature (28) seat (12i) and snap-in securing ramps (12k, 12m) that retain a leaf spring (26) extending through a slot (28a) in the armature (28) forms a subassembly that is inserted into an upper housing part (2) that has slots (2v, 2w, 2x) into which stationary contacts (6, 8, 10) are inserted. An encapsulated coil subassembly (38) having terminals (42, 44), a bobbin (40) and a coil (4) and a return spring (36) snap-in assembled thereon is placed over the armature (28). An E-shaped magnet (46) having shading coils (48, 50) on its poles is inserted through the holes in the coil assembly (38). A frame (52) is placed over the magnet (46) and snap-in coupled to the upper housing part (2) to complete the assembly of the contactor.Thin portions (38r) on the legs (38m, 38n, 38p, 38q) of the molding material encased coil (38) are resiliently deformed as the frame is pressed into snap-in engagement to take up any looseness between the parts.
