Abstract
An electromagnetic relay has a coil body with a core yoke formed from flat stock with a core leg extending through the coil body. A yoke leg, also formed from the same piece of flat stock, is disposed over or next to the coil in a plane which is at a right angle relative to the plane of the core leg. An armature is disposed at the free end of the yoke leg, forming a working air gap with the free end of the yoke leg and being mounted for movement on a leaf spring pivotable about a bearing location. The free end of the armature forms the contact spring which cooperates with a stationary contact element. A connection element functioning as a terminal is also integrally formed from the same piece of flat stock. Additional coil connection elements are secured in the coil body by being plugged therein. The relay assembly is mounted on a base which forms a portion of the housing in combination with a cap placed over the base covering the assembly.
