Abstract
A test probe for effecting temporary electrical connection to circuit terminals of miniature integrated circuits or like elements with small inter-terminal spacings. The probe has an insulative tip having a cross-sectional dimension smaller than the space between adjacent terminals. In an axially extending groove in the tip is a stiff wire, and a mechanism is provided for controllably moving the wire out of the groove after the tip has been inserted between two terminals. When the wire moves out of the groove, it contacts one of the electric terminals and wedges the insulative tip against the adjacent terminal so as to retain the probe in place.
