A test probe for the testing of electrical circuits and circuit boards comprises a probe head (52) breakably coupled to an elongated probe arm (51). The breakable coupling is achieved by securing a first ring (63) to the probe arm and a second ring (60) to the probe head. The first and second rings may be respectively made of magnetic material and magnetizable material (or vice versa) thereby achieving a magnetic breakable coupling between the head and the arm. The probe head may comprise one or a plurality of probing pins (54,55) depending upon the type of circuit under test. The break-away feature of the test probe prevents any shearing of a solder connection as well as any damaging of the circuit boards, and/or of the probing pin or pins (FIG. 5).

A test probe for testing electrical circuits mounted on a circuit board comprising: an elongated arm extending substantially along a longitudinal direction; and a probe head having at one end thereof at least one probe pin and having the other end breakably coupled to one end of the elongated arm such that said probe head and said arm are magnetically coupled in substantial alignment along said longitudinal direction, and are breakably uncouplable away from each other in directions away from said longitudinal direction, whereby said at least one probe pin may be deflected prior to any damaging of the circuit board, the electrical circuit under test, or the probe pin.
