ABSTRACT:
A pre-loaded compression spring assembly is described which preferably includes a compression spring, a base plate to support one end of the spring, and a flexible retention member which extends over the opposite end of the spring and which is adapted to retain the spring in a pre-loaded condition on the base plate. The spring assembly is compressed when force is applied to the upper end of the spring. The spring assembly has a variety of uses, including for example use in circuit board testing apparatus.
