摘要

Test probe with a finger tester fora probe member (27) for electrically contacting a contact point of a circuit board to be tested (37),an actuator with a permanently premagnetized core (17) and a coil element, which are movable relative to one another, wherein the vormagneti comprises the use of core (17) is fixed and the coil element (20) is movable, and the coil element (20) is mechanically coupled with the probe member (27) is connected, so that in the case of current circuit, the coil element (20) together with the probe member (27) is moved,the coil element (20) freely movably on the premagnetized core (17) is arranged.
