ACCESSORIES
Non-Turn Washer
The Series 61 bushing is 3/8 inches in diameter
and has a non-turn keyway to prevent rotation of
the switch body when the panel is cut to fit.
Another way to keep the switch from turning is to
use a non-turn washer. The washer is cadmium-
plated brass.
Part number:
12C1087-1
Part number:
SHH694-11,
302-2B stainless
steel, no plating
Shaft and Panel Seal
For shaft and panel seal version, the shaft is
sealed by an o-ring inside the bushing. The
panel is sealed by a flat gasket .045" thick at
the base of the bushing. The panel seals will
increase the behind panel dimension by .020"
to .040", when the switch is mounted. The panel
seal is silicon rubber.
