ABSTRACT:
The present disclosure describes an assembly which has particular application in the testing of printed circuit boards. More specifically, the assembly is comprised of an apertured holding plate which is registered with the board under test, and a probe subassembly. The latter includes a body member having a spring-actuated plunger type probe and a hook-like member. In operation, the body member is advanced toward the plate and the probe and hook-like member enter respective plate apertures. As electrical contact is made by the probe with a desired test location on the board, the hook-like member locks the body onto the plate. The body member is so formed that subsequent pressure applied thereto will release it from its locked condition.
