An improved knee probe for probing electrical devices and circuits is provided. The improved knee probe has a reduced thickness section to alter the mechanical behavior of the probe when contact is made. The reduced thickness section of the probe makes it easier to deflect the probe vertically when contact is made.

Here “thickness” is the probe thickness in the deflection plane of the probe (i.e., the plane in which the probe knee lies). The reduced thickness probe section provides increased design flexibility for controlling scrub motion, especially in combination with other probe parameters affecting the scrub motion.
