To achieve optimal locking of the spring plungers, the maximum distance a between the ball button and the spring plunger should not be excee- ded. The maximum distance a is calculated from the difference between the compression w of the selected plunger and the indentation depth s of the ball in the recess. These ball buttons are especially recommended for use with spring plungers with high spring loads.
