GN 923.7 flat-faced solid disk handwheels are distinguished by their modern design. These handwheels 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 must be pulled upward 90° against the torsion spring, to a stop, and then pushed axially against the spring pressure into its hold position. By maintaining the forward thrust on the handle, the handwheel can easily be rotated. When the handle is released, the spring returns it back to the retracted position.
