ABSTRACT:
A spring-loaded contact pin for testing a plurality of closely spaced contacts of a test sample includes a casing in which a plunger is movably guided and under the influence of a spring in tension. In order to allow a simultaneous testing of these contacts, the casing as well as the plunger of the contact pins have an oblong cross section which means that the dimension in one direction is longer than the dimension in a direction normal to the one direction.
