Rotary Switches
Multi-Deck Rotary Switches
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

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.
