Explosion-Proof Switches
Single-Conduit
Connect Switch*
* See page A124 for double conduit connect switches.
EX switches feature the smallest UL-listed
housings available for use in hazardous lo-
cations. Flame paths within the housing
cool exploding gases below the kindling
temperature before they reach the explosive
gases surrounding the housing.
The enclosed switching unit, which is held in
place by screws, is accessible when the
cover plate is removed. A tapped conduit

of EX listings (pages A122-A123); while a
second group (page A124) has a conduit
opening in each end of the switch.
These switches are not sealed against liq-
uids and are not intended to be subjected to
liquid splash or for outdoor applications. If a
sealed explosion-proof switch is required,
refer to the type CX and LSX.

FEATURES
NEMA
NEMA standards: 1, 7 and 9.
UL listed and CSA certified: Class I, Div. 1,
Groups B, C and D (Group B - only as noted
in order guides); and Class II, Div. 1, Groups
E, F and G.
Also refer to NEMA application note in the
Reference Standards section at the rear of
this catalog.
TEMPERATURE RANGE
EX switches are for use in a temperature
range of – 40 to 160 F (– 40 to 71 C). For
applications outside these limits, please call
the 800 number.
ACTUATORS
Roller arm versions are designed for cam or
slide operation. Listings include clockwise
and counterclockwise actuation. Levers are
adjustable through 360 . The roller is non-
sparking material.
The cross-roller arm switch is for use where
the operating mechanism approaches from
a direction perpendicular to the longitudinal
axis of the switch.
The overtravel plunger has a case harden-
ed, radius tipped, push-rod plunger guided
by a sturdy bushing.
The manually operated switch has a large
paddle-shaped actuator.
REPLACEMENT PARTS
Available replacement parts are listed on
page A125. An installation sheet packed
with each switch describes these parts in
detail and explains how they are installed.
