Toolless fastening mechanism

摘要

Methods and apparatus disclosed for providing a fastener that can hold suitably flat planar objects. No tools are required to actuate the fastener. The fastener holds the object with a predetermined range of force, determined by a built-in spring when actuated. The fastener is particularly suited for fastening Printed Wiring Boards (PWBs) in an electronics enclosure, and holds the PWBs in position, as well as providing electrical coupling of a voltage supply used on the PWB to the electronic enclosure.
