Abstract
A measurement probe has a spring loaded probe assembly and a pressure sensor disposed in a housing. The pressure sensor forms an electrical switch for passing an activation signal to a EOS/ESD protection module in response to axial movement of the housing relative to the probe assembly. A first compressive element produces a first pre-loaded compressive force and an increasing compressive force on the probe assembly and a second compressive element produces a second pre-loaded compressive force and an increasing compressive force on the probe assembly subsequent to the first increasing compressive force.
