Abstract: The disclosed concept relates to an overload relay and, more specifically, to an overload relay switch having a reduced number of components and less complex components. The reduced number of components includes the lack of a return spring on the manual actuators. Further, the relay switch member, which was typically a snap switch conducting member structured to change its configuration, is a substantially flat blade. Further, a circuit is used to detect an over-current condition and a solenoid actuates the relay switch assembly, thereby eliminating the need for a mechanical over-current detection and switch actuation device.
