1. Vorrichtung zur Herstellung eines elektrischen Kontaktes zwischen einer Prüfeinrichtung und einem zu prüfenden, mit elektrischen Leitern ausgestatteten Prüfling, wobei das freie aktive Ende des Kontaktes stiftförmig und zur Aus­ übung eines Hubes aus einer nicht kontaktierenden in die kontaktierende Stellung ausgebildet ist, wobei das dem Kon­ taktende (Tastkopf) gegenüberliegende Ende des Kontaktstif­ tes als pneumatisch betätigbarer, von einer Rückstellfeder belasteter Kolben in einem den Zylinder bildenden Gehäuse ausgebildet ist, dadurch gekennzeichnet, daß zwischen Kolben (7) und dem Gehäuseende (14) ein weite­ res federbelastetes, hohlzylindrisches, gegenüber dem Ge­ häuse (2) elektrisch isoliertes Stößelelement (17) vorgese­ hen ist, wobei bei Aufbringung eines pneumatischen Druckes über einen Stellweg der Kontakt zwischen federbelastetem Stößelelement (17) und Kontaktstift (4) aufrechterhalten bleibt und nach weiterem Stellweg das Stößelelement (17) und der Kontaktstift (4) zur Kontaktunterbrechung außer Eingriff gelangen.1. An apparatus for making an electrical contact between a test device and a test object to be tested, equipped with electrical conductors, the free active end of the contact being pin-shaped and designed for exercising a stroke from a non-contacting position into the contacting position, the Con clocking (probe) opposite end of the Kontaktstif tes is designed as a pneumatically actuated piston loaded by a return spring in a housing forming the cylinder, characterized in that between the piston ( 7 ) and the housing end ( 14 ) a wide res spring-loaded, hollow cylindrical, Compared to the Ge housing ( 2 ) electrically insulated plunger element ( 17 ) is hen, whereby when a pneumatic pressure is applied over a travel path, the contact between the spring-loaded plunger element ( 17 ) and the contact pin ( 4 ) is maintained and after a further travel path, the plunger element ( 1 7 ) and the contact pin ( 4 ) disengage to interrupt the contact. 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß das Stößelelement (17) und/oder das Gehäuse (2) mit ei­ nem elektrischen Anschlußkontakt (19, 20) ausgerüstet sind.2. Device according to claim 1, characterized in that the plunger element ( 17 ) and / or the housing ( 2 ) with egg nem electrical connection contact ( 19 , 20 ) are equipped. 3. Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß im dem Stopfen (3) abgewandten Bereich des Gehäuses (2) ein elektrisch isolierender Hohlzylinder (13) angeordnet ist, der im Inneren von einem rohrförmigen Teil (11a) des pneumatischen, elektrisch leitenden Anschlusses (11) ausge­ kleidet ist.3. Apparatus according to claim 1 or 2, characterized in that an electrically insulating hollow cylinder ( 13 ) is arranged in the region of the housing ( 2 ) facing away from the stopper ( 3 ), the inside of a tubular part ( 11 a) of the pneumatic, electrically conductive connection ( 11 ) is clad. 4. Vorrichtung nach Anspruch 3, dadurch gekennzeichnet, daß die Rückstellfeder (16) des weiteren Stößelelementes (17) bereichsweise im rohrförmigen Teil (11a) und bereichs­ weise im weiteren Stößelelement (17) positioniert ist.4. The device according to claim 3, characterized in that the return spring ( 16 ) of the further plunger element ( 17 ) is partially positioned in the tubular part ( 11 a) and partially in the further plunger element ( 17 ). 5. Vorrichtung nach einem der vorangehenden Ansprüche, dadurch gekennzeichnet, daß der isolierende Hohlzylinder (13), z. B. ein Kunststoff­ element, als Abschluß des pneumatischen Zylinderraumes (15) des ersten Kontaktstiftes (4) ausgebildet ist.5. Device according to one of the preceding claims, characterized in that the insulating hollow cylinder ( 13 ), z. B. a plastic element, as the end of the pneumatic cylinder chamber ( 15 ) of the first contact pin ( 4 ) is formed.
