Abstract
Probe pins are mounted on a housing in a manner which deflects the same and induces a preload therein. Upon the pins being brought into contact with a surface, the preload immediately increases the amount of contact pressure which is developed for a given amount of overdrive. In one embodiment the probe pin has both ends secured to the housing. A V-shaped portion is formed in the pin and used as the contact point. The manner in which the probe is secured, bends a portion of the pin proximate the contact point and produces a preload. As the other end is also secured, the preloading is augmented and contact point is prevented from undergoing lateral movement away from the housing on which it is secured.
