ꢀ STATUS INDICATOR EQUIPPED SWITCHES
Any of the WL switches above can be ordered with a neon or LED indicator that shows normally open and normally closed status. For a
neon indicator, add "-LE" to the end of a part number, for example, WLD2-TSLE. For an LED indicator, add "-LD" to the end of a part
number, for example, WLCA2-TSLD.

Construction
Proper Operation Zone Markers
Two raised markers on the shaft
housing indicate the proper limits
for normal operation to simplify
installation.
Roller
Sintered stainless steel with self-
lubricating bearing resists wear.
Lever
Too much Overtravel, adjustment needed.
Aluminum alloy resists corrosion.
Normal operation
Too little Overtravel, adjustment needed.
Normal operation
Roller Lever Mounting Screw
Too much Overtravel, adjustment needed.
Operating Head
Roller lever, rod lever and side
plunger types may be locked in
at any of four 90° positions.
Cover Seal
O-ring provides a high
degree of sealing.
Shaft Seal
O-ring provides a high
degree of sealing.
Terminal Screws
Four M4 screws
Insulation
Material provides insulation and
seals out corrosive gas.
Axis Bearing
Assures smooth plunger movement.
Cover Mounting Screws
Self-retaining Phillips head
screws will not fall out.
Built-in Switch
Long mechanical life of 15
million operations, minimum.

360°.
ꢀ ROTARY ACTUATOR POSITIONING
Actuators for rotary switches such as
WLCAꢀ-TS roller lever and WLCL-TS rod
lever switches can be positioned within a
360° range. Loosen the Allen-head set bolt
on the side of the actuator, position the
actuator, then tighten in place.
ꢀ OPERATING HEAD POSITIONING
The operating head of many switches can
be set to four 90° positions to match
installation requirements. Loosen the four
Phillips head screws on the operating
head, and lift the head off. Then, position
with the shaft in the desired direction.
Replace the four screws to fasten the
operating head. Applicable switches
include those with roller levers (WLCAꢀ-
TS), rod levers (WLCL-TS), horizontal
plungers (WLSDꢀ-TS) and roller plungers
(WLD2-TS and WLD28-TS).

the operating direction, loosen the four
screws on the switch head. Then, lift off the
head. The plunger marker inside is set
parallel with the face plate, as shown at right.
Turn the plunger so the marking faces left for
CW or right for CCW as shown. Replace the
actuator head in the direction suitable for the
installation and tighten the four screws.

ꢀ ROLLER LEVER ACTUATOR POSITIONING
The roller(s) on roller lever actuators may
be faced inward toward the operating head
or use the more typical installation with the
roller lever facing away from the body. To
change the actuator position, loosen the
Allen-head set bolt, pull the actuator off,
and reposition it on the shaft. Then, tighten
the set bolt at the desired angle.

ꢀ ADJUSTING LEVER AND ROD LENGTH
Switches with adjustable lever and rod
actuators can be set to desired length by
loosening the Allen-head set screw, setting
the length. Then tighten the set screw.

ꢀ STATUS INDICATOR EQUIPPED SWITCH OPERATION
WL switches are available with neon lamp
Indicator lights
(WLꢀꢀꢀꢀ-TS-LE) or LED (WLꢀꢀꢀꢀ-TS-
when NC contacts
LD) status indicators for easy monitoring
and troubleshooting. They come factory-
set for Normally Open operation ON. It is
release (when
actuator rotates or
is pushed down)
easy to change the status to Normally
Closed operation ON. See the Installation
section for details.
Indicator is lit
while actuator is
free, then goes off
when NO contacts
close: when
actuator rotates or
is pushed down
When connecting a limit switch to a
programmable controller, select the neon
lamp or LED with the smallest leakage
current. Refer to the table at right.

Overtravel Type
Overtravel type limit switches offer a longer
overtravel (OT) to accommodate different
cam shapes. The key difference between
"standard" and "overtravel" is in the angle
of operation: overtravel types can operate
at 90° on either side of the center point.
Standard types are recommended for
operation at 45° on either side of the center
point. However, overtravel type switches
cannot be expected to provide 90°

High-Precision Type
The key differences between "high-
precision" and "standard" limit switches
are in the pretravel (PT) ratings and the
repeat accuracy. High-precision
switches have a pretravel (PT) of 5°
compared to 20° for standard switches.
The repeat accuracy is best compared by
referring to the graph at right. High-
precision switches are ideal for position-
ing control in machine tools and other
applications.
