ABSTRACT:
The relay includes a coil assembly enclosed in a top enclosure made from insulating material. The coil assembly includes a spooled coil body, a core, pole shoes and winding terminal elements assembly and is disposed above a pivoting armature which is connected to contact springs via a carrier element of insulating material. The relay also includes a base made from insulating material and which contains terminal paths for stationary cooperating contact elements as well as contact terminal elements. The armature is disposed above the base via bearing supports and bearing bands integrated in the contact springs. A frame is disposed over the base and forms a housing for the relay together with the base and with the top enclosure. The housing encapsulates the contact space of the relay, wherein the frame with the base represents the lower housing part and the top enclosure for the coil assembly represents the upper housing part.
