way operation
CX switches are built especially for outdoor
use in hazardous atmospheres. These en-
closures are constructed to withstand the
pressure of an internal explosion. Flame
paths cool the exploded gases to a point
less than the lowest safe operating temper-
ature of the surrounding gas.
O-ring seals make the enclosure weather-
proof but are outside of required flame paths
so explosion proof requirements are main-
tained.
Analog output: either resistive or 4-20 mA is
available.
Operating temperature range is –25°to
+85°C (–13°to 185°F).
NEMA standards: 1, 3, 4, 4X, 6, 6P, 7, 9 and
13.
UL listed: Class I, Div. 1, Groups B (14CX,
16CX, 24CX, 26CX, 36CX, and 84CX only), C
and D; and Class II, Div. 1, Groups E, F and
G. CSA certified: Class I, Div. 1, Groups B
(14CX, 16CX, 24CX, 26CX, 36CX and 84CX
only), C and D; and Class II, Groups E, F and
G.

ASSEMBLIES
These assemblies are factory adjusted to
the same operating characteristics as a new
CX switch. They include components sub-
ject to mechanical or electrical wear: basic
switches, cam wheels and followers, and
springs.
To order, change the first number in the
complete switch catalog listing to 9 for ro-
tary switches and 10 for plunger switches
with short housings.
Example:
Rotary switch 12CX5
Replacement J92CX5
Plunger switch 36CX2
Replacement J106CX2
Note: Basic switch assemblies for rotary ac-
tuated switches, with or without shaft restor-
ing force, will be the same.
For example:
11CX1 and 11CX11 use 91CX1.

CORROSIVE ENVIRONMENTS
80CX switches have rugged bronze hous-
ings which are resistant to salt water and
other corrosive environments. They comply
with the NEMA 4X requirement for protec-
tion against corrosion, in addition to NEMA
enclosure standards met by other CX
switches. O-ring seals make the enclosure
weather-proof, but are outside of required
flame paths so explosion-proof require-
ments are maintained.
STAINLESS STEEL LEVER ACTUATORS
These levers match the corrosion resistance of the 80CX housing. Non-sparking rollers
must be used in hazardous locations.

DIRECT COUPLING
CX switches are available with a 3⁄8inch
diameter by 3⁄4inch long flatted shaft which
conforms to standard NEMA motor shaft
specifications. It accepts commercially
available shaft couplers, permitting easy,
direct coupling to most equipment actua-
tors.
To specify a ‘‘direct-couple’’ CX switch, add
-DO1 to catalog listings shown in the order
guides, i.e. 11CX12-DO1. Pricing is the same
as for unmodified versions.
