Special feature command shaft
Length is measured from the mounting surface to the free end of the shaft. The screwdriver slot is
aligned with the wiper within ± 10°. Special shafts are available, in accordance to drawings supplied
by customers. We recommend that customers should not machine tool shafts, in order to avoid
damage. Bending or torsion of terminals should also be avoided.
