ABSTRACT:
An electromagnetic relay includes a coil having a winding between two coil flanges wherein one of the coil flanges forms a pocket-shaped contact chamber. An angled yoke is provided for the coil on which is seated a flat armature that is secured by an armature retaining spring. Male retaining members extending from the angled yoke mount the retaining spring and can be bent to set the armature restoring force. Separation of the moving parts of the relay at an end face of one coil flange from the winding enables casting compound to fill the winding space and seal the contact chamber.
