A method for manufacturing a relay comprising the steps of:
- placing a contact spring terminal pin and a plurality of fixed contact carriers and a plurality of coil terminal pins into a coil body injection mold for producing a plurality of respective wire elements;
- cutting at least a portion of each of said wire elements;
- forming a coil body by injecting plastic into the coil body injection mold, said coil body including a coil tube having a first and a second coil tube end and two coil flanges, said two coil flanges including a first coil flange and a second coil flange being connected to said respective first and second coil tube ends, said first coil flange including a switch space, said switch space including each of said plurality of fixed contact carriers being embedded into said first coil flange, said coil body further including said contact spring terminal pin being embedded in one of said two flanges;
- welding a fixed contact to each one of said fixed contact carriers;
- attaching a coil, a core and a yoke having a yoke bearing edge to said coil body;
- placing an armature against said yoke bearing edge, said armature being mounted to a contact spring, said contact spring including a
- contact spring angled member having a first, second and terminal contact spring end, said first contact spring end embracing said yoke bearing edge, said second contact spring end being positioned
- adjacent to each of said fixed contact carriers;
- and
- connecting said contact spring terminal end to said contact spring terminal pin.
