<p>The tube has upper/lower resistance contact plungers (9, 10) axially movable and electrical conductively guided into upper/lower plungers (4, 5). The resistance plungers are temporally operated by the respective plungers (4, 5), where the resistance contact plungers are axially supported on the respective plungers during the movement of contact plungers from an end position into another end position. Electrical connection of a contact plate (6) and electrical connection of the resistance contact plungers with corresponding resistance contact plates (11, 12) do not exist in the end positions.</p> |
