Abstract
A differential measurement probe has spring loaded probe assemblies and a pressure sensors disposed in a housing. The pressure sensors forms an electrical switch having an electrical AND function for passing an activation signal to a EOS/ESD protection control module in response to axial movement of the housing relative to the probe assemblies. First compressive elements produces first pre-loaded compressive forces and increasing compressive forces on the probe assemblies and second compressive elements produces second pre-loaded compressive forces and increasing compressive forces on the probe assemblies subsequent to the first increasing compressive forces on the probe assemblies.
