for frequent adjustment) than drive trains with plastic parts
MICRO SWITCH™ LSX Series
Hazardous Area Limit Switches
MICRO SWITCH™ LSX hazardous area switches are designed for use in adverse environments. They are approved for use in
hazardous locations and NEMA classied atmospheres because their rugged housings have integral ame paths. These ame
paths force internal expanding gases to cool below external atmosphere ignition temperatures before they leave the housing. The
LSX also features tracking interchangeability with MICRO SWITCH™ BX Series Hazardous Area switches. An optional mounting
plate provides the same tracking and mounting as the standard HDLS Series (heavy-duty limit switch).
The majority of HDLS operating heads and circuitry options are available for the LSX Series. The rotary actuated LSX series
products are designed for use with levers that have non-sparking actuators due to the potentially hazardous environment. The
other styles of LSX Series switches which are the plunger actuated and wobble actuated products incorporate an integral non-
sparking actuator.

Features
and Benefits
Features
and Benefits
DESIGN FLEXIBILITY
MICRO SWITCH™ LSX limit switches’ field adjustability (CW-CCW operation,
rotatable operating head) assists in matching the switch to the application.
Available with momentary, maintained, sequential, or center neutral action.
UNIQUE DESIGN FEATURES
The head design is keyed for more secure head-to-body retention with the
head indexable in any one of four positions 90° apart. Captive mounting screws in
the heads help prevent the loss of screws during replacement or repositioning of
the head. Self-lifting pressure plate terminals save wiring time.
WITHSTANDS MANY CAUSTIC ENVIRONMENTS
A die-cast zinc head and aluminum body make the LSX suitable for indoor and
outdoor applications. A diaphragm seal between the head and body is designed
to provide an extra measure of protection. Switches remain functional when
exposed to many severe environments and caustic chemicals.
OPTIONAL SEALS
Standard seals are suitable for most applications, but optional fluorocarbon
or fluorosilicone seals are available for many harsh chemical, high or low
temperature environments.
DESIGNED TO CONTROL LOW-VOLTAGE DC APPLICATIONS
Hazardous area switches are available with a choice of silver or gold-plated
contacts to handle a variety of electrical load requirements from low energy to
power-duty control.

MICRO SWITCH™ LSX SERIES OPERATING
HEADS
SIDE ROTARY: Heads may be positioned in any one of four posi-
tions, 90° increments. All are momentary action except maintained
head (LSXN Series).
LSXA - Standard: 60° minimum over-
travel, 15° maximum pretravel,
5° (single pole) and 7° (double pole) maxi-
mum differential travel.
LSXR - Low operating torque: 60° minimum overtravel, 15°
maximum pretravel, 0.19 Nm [1.7 in-lb] maximum operating
torque.
LSXN - Maintained contact: Maintained on counterclockwise
rotation and reset on clockwise rotation, and vice versa.
LSXP - Low differential: 68° minimum overtravel, 9° maximum
pretravel, 3° (single pole) and 4° (double pole) maximum differen-
tial travel.
LSXH - Low torque, low differential travel: 68° minimum
overtravel. Features low operating torque and narrow differential
travel.
LSXL - Sequence action: 48° minimum overtravel. Delayed
action between operation of two poles.
LSXM - Center neutral: 57° minimum overtravel. One pole
operates on the clockwise rotation, and the other pole on the
counterclockwise rotation.
LSXU - Low pretravel: 5° max. pretravel, 70° min. overtravel.
TOP ROTARY: Available levers provide greater versatility. Heads
may be positioned in any one of four positions, 90° increments. All
are momentary action.
LSXB: With 100° minimum overtravel.
Various levers that t side rotary shafts may
be used on the top rotary shaft. Switch is
suitable for use when increased overtravel
is required.
HIGH TEMPERATURE/CHEMICAL RESISTANT
SWITCHES
Completely uorocarbon (FC)-sealed switches have a full FC body
gasket covering the switch cavity. Rotary types have an extra
FC seal on the operating shaft, while plunger versions have FC
boot seals. They are designed for use in applications where the
environment includes re-resistant synthetic uids. In addition,
the FC-sealed switches may be used with such industrial uids
as Cellulube, Fyrquell, Houghto-Safe, Pydraul, and other special
cutting and hydraulic uids. The additional FC seals also promote
extended operating life for rotary-actuated LSX switches in applica-
tions where the temperatures are normally -12 °C to 121 °C [10 °F
to 250 °F].
To order, insert the additional letters Y and C in the appropriate
places in the standard catalog listing, as shown below:
LSXA3K standard, side-rotary plug-in switch
LSXYAC3K completely FC-sealed version of LSXA3K
LOW TEMPERATURE SWITCHES
All forms of LSX limit switches are also available in low-temperature
construction. Design features include uorosilicone diaphragm,
shaft seals, and external boot seal (where applicable).
To order, insert the additional letters Y and B in the appropriate
places in the standard catalog listing, as shown below:

LSX Series
TOP PLUNGERS: Available with 4,83 mm [0.19 in] minimum
overtravel. Top pin plungers are offered in pin plunger, an
adjustable plunger, and a roller plunger.
LSXC - Top pin plunger: A copper alloy
plunger for in-line actuating motion. Oil-
tight seals on plunger and between the
operating head and housing are designed
to keep out coolant, dust, and chips.
Momentary action.
LSXD - Top roller plunger: A copper
alloy roller plunger is adjustable to 90°
angles to accept cam or slide operation
from any of two directions. Boot seal on
the plunger. Momentary action.
LSXV - Adjustable top pin plunger: A
copper alloy adjustable plunger is designed
to simplify the application and decreases
installation time. The operating points of
the switch can be adjusted from 65,66
mm to 72,0 mm [2.585 in to 2.535 in].
Seals are the same as the pin plunger.
Momentary action.
MICRO SWITCH™ LSX SERIES OPERATING HEADS
SIDE PLUNGERS: Made of non-sparking copper alloy. Available
with 4,83 mm [0.19 in] minimum overtravel. Side plungers are of-
fered in plain plunger, an adjustable pin plunger, and a
roller plunger.
LSXE - Side pin plunger: A copper alloy
plunger for actuating motion inline with the
plunger travel. Actuating head may be ro-
tated in any of four positions, 90° apart. A
boot seal on the plunger and a gasket seal
between the head and housing is designed
to keep out coolant, dust, and chips. Mo-
mentary action.
LSXF - Side roller plunger: A copper
alloy roller plunger ts close quarters under
cams and slides. The head may be rotated
in any of four positions, 90° apart. The
roller can be turned vertical or horizontal to
the switch. Boot seal on plunger. Momen-
tary action.
LSXW - Adjustable side pin plunger:
Has the same features of the side plain
plunger plus the means to adjust the oper-
ating points of the switch from 41 mm to
47,4 mm [1.615 in to 1.865 in]. Momentary
action.
WOBBLE LEVER ACTUATING HEADS: Heads come with
either a Delrin® plastic rod or a copper alloy cat whisker. Any
movement of the lever (except pull) will actuate the switch.
LSXJ - Plastic rod:
Recommended where
possible scratching or
marring by the actuator is
to be avoided.
LSXK - Cat whisker:
Copper alloy actuator de-
signed for low operating
force applications.

ASSEMBLY MODIFICATIONS
Momentary action rotary switches can be furnished in other than
the normal assembled conditions. To specify modications, add the
numbers shown below to the catalog listings. Modication number
sufxes are:
1 Clockwise actuation only
2 Counterclockwise actuation only
3 Shaft to right of switch front
4 Shaft to left of switch front
5 Shaft to back of switch
For example,
Catalog listing LSXA3K23 is a LSXA3K switch adjusted for counter-
clockwise actuation only. The operating shaft is to the right side of
the switch when viewing it from the front (label side). No lever.
PLUNGER ASSEMBLY MODIFICATIONS
Add the following modication numbers to the catalog listing in the
plunger switch:
3 Side plunger to right of switch front
4 Side plunger to left of switch front
5 Side plunger to back of switch
6 Roller on top plungers perpendicular to mounting surface
8 Roller on side plungers in vertical position
For example,
Catalog listing LSXF3K3 is a LSXF3K switch with the side roller
plunger to the right side.
ADAPTER PLATE
Catalog listing LSXZ4022 adapter plate enables the NEMA-rated,
explosion-proof LSX Series to be mounted on existing HDLS
mounting holes. The LSX has a recessed back into which the
adapter plate ts and mounts, using two screws (furnished)
