A coil form (1) is injection moulded to form the base body of the relay. At least one fixed contact carrier (3,4), one contact-spring contact pin (5) and coil contact pins (9,10) embodied as wire sections in the form of drawn semifinished products are introduced into the mould and extrusion-coated. The core (16) can also be embedded into the material of the coil form (1) if so desired. This dispenses with assembly processes involving the abrasion of plastic particles which can later become deposited on the contacts. All connector pieces can be mounted in a cost-effective manner in the injection mould, requiring as little material as possible by virtue of the fact that there is no wastage when the semi-finished wires are separated. |
