Abstract
An improved electromechanical switch designed to operate at frequencies from DC through microwave has terminal probe tips that are formed from an alloy of noble metal and contoured with a pattern of peaks and valleys in order to provide better contact wiping operation and capture of wear debris. The switch incorporates damper elements to reduce switching contact bounce, thus providing increased contact life as well as higher quality signal switching.
