[QUOTE="chrisc, post: 1067775, member: 746"] Is this the method whereby current limiters operated, where when a metal strip moved away from a contact point, electrical continuity ceased? A friend has a reciprocating cutter for handling large blocks of steel, like a railway line. Inside a small box is this bimetal strip and if the current used by the motor becomes excessive due to a possible stall, it disconnects. The machine was made in the 1950s and today a solid-state current sensing circuit would probably be used The strip consists of brass and lead, riveted one end Am I on the right track? [/QUOTE]
