Spring Plungers smooth, without collar, with moveable ball
EH 22081.
Spring plungers can be used for locating or for applying pressure, as a detent or for ejection.
The running of the ball minimises wear on the counterpart, this also results in a positive locking behaviour depending on the counterpart.
Another advantage of the plastic ball is the electric insulation.
