Abstract
A method of producing a plurality of individual contact spring assemblies for use in an electromagnetic relay in which movable and fixed contact springs for each assembly are held by a molded resin base comprises the steps of caulking a first set of contacts and a second set of contacts to a unitary sheet metallic blank and stamping out the movable and fixed contact springs from the metallic blank. The method further comprises the steps of bending the stamped-out movable and fixed contact springs into a predetermined configuration such that the fixed and movable contact springs are in opposition to each other and molding a base so that selected portions of the movable and fixed contact springs are embedded therein. Finally, the method comprises the step of cutting the fixed and movable contact springs from the metallic blank.
