SPECIAL FEATURES
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 shafts, in
order to avoid damage. Bending or torsion of terminals
should also be avoided.
