Patent ID: 7148709

Claim:
An electrical probe comprising: a. a rigid columnar structure extending between a peripheral end and a connect end along a central column axis; b. a suspension knee having: I. a base arm laterally connecting to said connect end and extending away from said column axis substantially to a lateral knee extension; II. a reverse arm continuing from said base arm extending from said lateral knee extension toward said column axis, but not reaching said column axis; III. a contacting tip at the end of said reverse arm, said contacting tip having a contacting face with a central tip axis having a non-zero tip offset relative to said column axis, wherein said tip is disposed at a location between said lateral knee extension and said column axis; wherein said tip offset is smaller than said lateral knee extension such that during application of a contacting force along said tip axis a first deflection of said base arm and a second deflection of said reverse arm counteract resulting in a predetermined scrub motion of said contacting tip; and wherein said suspension knee is freely suspending.
