ACCESSORIES
Non-Turn Washer
Shaft and Panel Seal
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.
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
baseofthebushing.Thepanelsealswillincrease
the behind panel dimension by .020" to .040",
when the switch is mounted. The panel seal is
silicon rubber.
