Abstract:
A contact for use in a test set which can be mounted to a load board of a tester apparatus. The contact, which serves to electrically connect at least one lead of a device being tested with a corresponding metallic trace on the load board, has a first end defining multiple contact points. As the test pin is rotated about an axis generally perpendicular to a plane defined by the contact, successive contact points are sequentially engaged by a lead of the device being tested. The test pin has a hard stop edge which engages a hard stop wall which limits its rotation movement. The bottom of the pin has a shallow convex curvature preferably with a flat region and the tip of the test pin has a chisel edge.
