Abstract
A gravity/spring assisted electrical current operated relay has electrical terminals constructed integrally with electrical contact blades. Continuous build-up of conducting particles from the arcing of contacts is prevented through slots and protrusions built into the body of the relay. A recess is provided at the bottom of a cavity holding the armature for receiving foreign matter. Longitudinal ribs are provided along the walls of the cavity to prevent binding of the armature as it moves within the cavity. The ribs also provide a space for foreign matter. A holder is provided to receive an electrical terminal remote from the field coil.
