 Handwheels GN 322.7 with retractable handle GN 598.7 are suitable for applications where the "handle must not remain in the operating position. 

In order to bring the handle into the operating position it has to be turned first through 90 to a stop against a torsion spring and then it is pushed against spring pressure into its hold position. By maintaining the forward thrust on the handle the handwheel can easily be rotated.

When releasing the handle the springs returns it back to the retracted position.
