TheSeries42/44Styles, whichincludetheletter"S"withthe
exceptionofstyle"HS",arewatertightsealedtothemounting
panel by utilizing the panel seal kit. These switches are built
with a front plate that does not have a non-turn tab. The
panel seal kit consists of a grooved hex nut, a keyed washer
and a keyed panel seal. The grooved hex nut is assembled
to the switch bushing. The keyed washer is slid down the
bushing slot and seated into the hex nut groove. The seal
is likewise assembled to the bushing and hex nut. The
keyed washer is required to provide seal integrity in the
bushing slot. When assembled to the panel, the grooved
nut, backing washer and seal require the same space as a
normal mounting nut. Hence, the seal kit does not alter the
dimensions. Panel seal kit includes a non-turn washer to be
used into a blind hole in the back panel. For panel seal kit
part dimensions, see ꢁccessories. Style "HS" switches use
a similar sealing method, except the integral assembly nut
retainsthepanelseal.ꢁllsealedstyleswitchesareprovided
with a shaft to bushing internal seal.
