Abstract
A manufacturing method for an electromagnetic relay whereby a base block 20 is monolithically molded to terminals 21-24 and connector tabs 62 provided in a lead frame 60. After separating the terminals 21-24 from the lead frame 60 and bending the terminals, a permanent magnet 30 and armature block 40 are assembled into the base block 20. A case 50 is then pressed down over the base block 20 to separate the base block 20 from the connector tabs 62 of the lead frame 60. Electrical inspection and aging treatment can thus be accomplished with the base block 20 connected to the lead frame 60, improving assembly precision and productivity.
