  • Patent number: 4553001
    Abstract: A probe for detecting contact with an object such as a workpiece includes a movable carrier having a first set of contacts mounted thereto and a fixed carrier having a second set of contacts mounted thereon. The first carrier is operably connected to a probe stylus and moves therewith when the probe stylus contacts an object thereby making or breaking electrical connection between one or more of the contacts. Each of the carrier members is made of a body of high flexural strength nonconductive material, preferably glass fiber reinforced plastic, to thereby simplify electrical insulation of the contacts as well as to insure repeatability of the probe measurements.
