Abstract
Leads of electronic components, such as dual-inline packages, are contacted for test purposes by opposed pairs of cantilever-spring contacts. The tips of each pair of contacts are offset with respect to each other when in position for testing so that they do not touch each other when a lead is absent. The opposed contacts provide equal forces on opposite sides of the leads, so that no lead support is required for testing, and also provide open circuits instead of shorted circuits when a lead is absent.
