ABSTRACT:
An electrical probe includes an electrically conductive member free to move in an electrically insulating shaft. The member is secured to the shaft at the proximal end by a resilient loop. The probe is held between the thumb and the forefinger so that the thumb presses against the loop. When the thumb is pressed against the forefinger, the loop is compressed and the member is extended down the shaft and beyond to the desired test position. The probe may include a hook at the distal end of the extendable member to grasp a wire or component for testing.
