OPTIONS
SPECIAL FEATURES
Lengths are measured from the mounting surface to the free end of shaft. Shaft slot is
aligned with the wiper within ± 10°. Special shafts are available, in accordance with
drawings supplied by customers. We recommend customers not to machine shafts, in
order to avoid damage. Bending or torsion of terminals should be avoided.
The type P12T with AB (old code M) or AJ (old code R) shaft can be provided with an
optional “DE” sealing hardware which ensures sealing of both the shaft and the
mounting panel. DE sealing hardware can be supplied in a separate bag.
