• Can be used over a wide range, from positioning to
workpiece detection.
• Easy to use because the stroke in the direction of revolution
can be set to an angle from 45° to 90° (varies by model),
and the lever can be set to any angle over 360°.
• High-sensitivity Switches with minimal movement before
activation (example: WLG2) and High-precision Switches
with high repeatability (example: WLGCA2) are available.

Plunger Models
• A wide range of operation is possible by attaching an
auxiliary actuator to a cam, dog, cylinder, or other part.
• High repeatability, good for positioning detection.
Roller plunger
Ball plunger
Coil spring
• The tip of the plunger is made of a steel ball, which can be
operated in any direction with no limitations.
• The ball plunger is convenient when the mounting side is not
aligned with the movement direction of the dog or the Limit
Switch is actuated by two dogs in X and Y directions.
• Operation from any direction over 360° is possible,
excluding the axial direction.
• Lowest activation force of the limit switches. Effective for
detection of non-uniform directions and shapes.
• Large tolerance for workpiece play because the actuator
absorbs movement after activation.

Note: Leakage current from indicator circuit may cause load malfunction (i.e., the load may remain ON). Make sure that the load operating current
is higher than the leakage current. For countermeasures, refer to technical support on your OMRON website.
*1. Light-ON when not operating means the operation indicator is lit when the actuator is free and is not light when the Switch contacts (NO) close
when the actuator rotates or is pushed down.
*2. The position of the positioning piece is not always the same. If using an L-shaped connector causes problems in application, use a straight
connector.

Operation indicator Switches
Basic Switches
Indicator Covers
Indicator
The indicator covered if outsert molded
from diecast aluminum and has outstanding
sealing properties.
The indicator is either a neon lamp or an
LED. Switches with LED indicators have a
built-in rectifier stack, so there is no
connection polarity.
Indicator Windows
Operating status (i.e., light-ON when
operating or light-ON when not operating)
depends on whether a neon lamp or an
LED is used.
Contact Spring
The built-in switch's terminal screws
are used to connect the indicator
terminal. Since the connection spring
(coil spring) is used for this connection,
it will not be necessary to connect the
indicator terminal. When a ground
terminal is provided however, a lead
wire must be used.
Light-ON when Operating/Not Operating
Lamp Holder
Indicators can be switched from light-ON
when operating and light-ON when not
operating, by simply rotating the indicator
holder by 180°.
(However, Direct-wired Connector,
Pre-wired Connector, Three-core, and
Four-core Switches cannot be switched to
light-ON when operating (NC wiring).)

Safety Precautions
• Constantly subjecting a Switch to vibration or shock can result in
wear, which can lead to contact interference with contacts,
operation failure, reduced durability, and other problems.
Excessive vibration or shock can lead to false contact operation or
damage. Install Switches in locations not subject to shock and
vibration and in orientations that will not produce resonance.
• The Switches have physical contacts. Using them in environments
containing silicon gas will result in the formation of silicon oxide
(SiO2) due to arc energy. If silicon oxide accumulates on the
contacts, contact interference can occur. If silicon oil, silicon filling
agents, silicon cables, or other silicon products are present near
the Switch, suppress arcing with contact protective circuits (surge
suppressor) or remove the source of silicon gas.
Precautions for Safe Use
• Be sure to ground. Otherwise electric shock may result.
• Do not touch charged switch terminals while the switch has carry
current, Otherwise electric shock may result.
• Do not disassemble the limit switch or touch inside of it under
supplying power,
Otherwise electric shock may result.
• Do not disassemble the limit switch or touch inside of it under
supplying power, otherwise there is the possibility that electrical
shock occurs.
• Do not touch the wire or rod type actuator in order to prevent injury.
• Connect a fuse which has 1.5 to 2 times higher breaking current
than the switch rated current to the switch in series in order to
prevent the switch from short-circuit damage.
Installing the Switch
• To install the Switch, make a mounting panel, as shown in the
following diagram, and tighten screws using the appropriate
tightening torque.
• On the occasion when using the switch with GB ratings, use a 10A
fuse that complies IEC60269, either type gG.
• The durability of switch is depends on the operating condition Be
sure to check the condition with actual using condition before
using, and use with the number of times of operating without a
performance problem.

• Otherwise, there is the possibility of spoiling the normal operation.
Do not drop the switch.
• Do not connect a Single Limit Switch to two power supplies that are
different in polarity or type. Risk of interference.
• Be sure to keep the load current less than the rated value.
Otherwise, there is the possibility that the switch may be damage
and/or burnout.
• Do not use the Switch by itself in atmospheres containing
flammable or explosive gases. Arcs and heating resulting from
switching may cause fire or explosion.
• Be sure to prevent the foreign materials such like a scrapped cable
intrusion in to the switch when wiring. Otherwise, there is the
possibility of spoiling the normal operation.
• Never wire to the wrong terminals.
• Do not store or use the switch with following place.

Using Switches for Micro Loads
Contact faults may occur if a Switch for a general-load is used to
switch a micro load circuit. Use switches in the ranges shown in the
diagram below. However, even when using microload models within
the operating range shown here, if inrush current occurs when the
contact is opened or closed, it may increase contact wear and so
decrease durability. Therefore, insert a contact protection circuit
where necessary.
For the WL-N, the P level is at the min. operating load of 5 VDC and
1 mA resistive load.
Note: The P level indicates the standard malfunction level at a
reliability level of 60% (λ60).
Where the humidity is very high and condensation may occur.
Where the vibration is too much
Where receiving direct sunshine.
(JISC5003) λ60 =0.1×10-6/operations indicates that the
estimated malfunction rate is less than 1/10,000,000
operations with a reliability level of 60%.
Where receiving salty wind.
For the WL01G@, the N level is a reference value at the min.
operating load of 5 VDC and 1 mA resistive load. An estimated
malfunction rate of 1/2,000,000 operations at a reliability level of 60%
is indicated as a reference value.
• Do not disassemble and/or modify the switch at anytime.
Otherwise, there is the possibility of spoiling the normal operation.
• Do not apply the force such like deformation and/or degeneration
to the switch.

Basic Switches
• Use M3.5-nylon insulation covered crimp terminals (round type) for wiring.
Ex.) V1.25-M3.5(RAP1.25-3.5) (J.S.T. Mfg. Co.,Ltd.)
• Appropriate wire size is AWG16 (1.25 mm2).
• Do not supply electric power when wiring. Otherwise electric shock
may result.
Microload Applications
• The WL-N Basic Models contacts can be used both for standard
loads and microloads, but once a contact has been used to open
and close a load it can no longer be used for lower loads. Doing so
will damage the contact surface and reduce contact reliability.
• If an inrush current or other sudden load occurs during a switch
operation, the switch will begin to degrade severely which can
result in reduced durability. Use a contact protection circuit if
required.
• Do not pull out the wires with excessive force. It may cause of
coming off the wire.
• Use crimp terminals for wiring.
• In the case of indicator unit, to avoid interference
between lump unit and crimp terminals, wire
according to right wiring figure.
Attach the indicator unit spring to terminal screw
certainly, otherwise it's possible to be destroyed or
shorted.
Indicator
• The ground terminal is only installed on models
with ground terminals.
Indicator-equipped switch has contacts and indicator in parallel.
When contacts are open, leakage current flows through the indicator
circuit and may cause load's malfunction. Leakage current may cause
load malfunction (i.e., the load may remain ON). Make sure that the
load operating current is higher than the leakage current. For
countermeasures, refer to technical support on your OMRON
website.
High-sensitivity and High-precision Switches
• Use 1.25-mm2 lead wires and M4-insulation covered crimp
terminals for wiring.

• Make sure that the actuator does not exceed the OT (overtravel)
range, otherwise the Limit Switch may malfunction. When
mounting the Limit Switch, be sure to adjust the Limit Switch
carefully while considering the whole movement of the actuator.
Operation
• Carefully determine the position and shape of the dog or cam so
that the actuator will not abruptly snap back, thus causing shock.
In order to operate the Limit Switch at a comparatively high speed,
use a dog or cam that keeps the Limit Switch turned ON for a
sufficient time so that the relay or valve will be sufficiently
energized.
