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.
For rapid response – off the shelf service,
all bold face listings are normally stocked

ORDER GUIDE
As factory assembled, all basic switches
operate on clockwise and counterclockwise
rotation. Actuating mechanism can be field
adjusted for CW or CCW operation only. No
tools are required.

1Basic switches operate nearly simultane-
ously in multiple switch devices.
2Shafts of devices without shaft restoring
force can be rotated through 360°.
Basic switches will be in operated mode
through two 105°sections.
Eight side mounting holes can be tapped
