SHAFT AND PANEL SEAL: Srs. 42 & 44
Standard Style
The Series 42/44 Styles, which include the letter "S" with the
exception of style "HS", are watertight sealed to the mounting
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 Accessories. Style "HS" switches use
a similar sealing method, except the integral assembly nut
retains the panel seal. All sealed style switches are provided
with a shaft to bushing internal seal.
SHAFT END
Termination
One-sided termination is standard for switches with 2 to 5
positions per pole. Two-sided termination is standard for
switches with 6 thru 10 positions per pole.

ADJUSTABLE STOP SWITCHES: Series 42 and 44
The standard and UL recognized switches are
also available with adjustable stops. Two
removable stop washers allow you to limit the
number of switch positions as needed. A knurled
nut is supplied to secure the washers if desired.
These switches have no bushing keyway.
All
other dimensions, ratings and characteristics
are the same as the standard fixed stop styles.
Although not military qualified, the adjustable
styles are useful in military equipment
prototypes. However, when submitting the
equipment for government approval, the fixed
stop qualified style should be substituted.
Equivalent Styles
For style 42A36, use 42D36,
For style 44A30, use 44D30
For style 42M36, use 42D36 initially
For style 44M30, use 44D30 initially
