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
brass, tin/zinc plated.
Part number: 12C1087-1
Part number: SHH694-11, 302-2B stainless
steel, no plating
DIMENSIONS In inches (and millimeters)
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.
