Precautions & Instructions

Turn off the power to CW series switches before installation, removal,
wiring and maintenance. Failure to turn power off may cause electrical
shocks or fire hazard.

Operating Instructions

Notes for Operation

When using the CW series switches in a
safety-related circuit of a control system,
observe safety rules and regulations of
each country concerning particular applica­tions of the actual machines and facilities.
Perform risk assessment before operation
to ensure safety.

Removing and Installing the Contact Unit

1. To remove the contact block from the opera­tor, push the yellow locking lever and turn it
to the left.

Locking Lever

When wiring, use wires of a proper size to meet the voltage and current
requirements. Tighten the M3.5 terminal screws to a tightening torque of

1.0 to 1.3 N·m. Failure to tighten the terminal screws may cause over­heating and fire.

Illuminated Pushbuttons and Pilot Lights

Removing the Lens

To remove the lens from an illuminated pushbutton
or pilot light, insert a flat screwdriver under the
flange of the lens at 90° from the TOP marking and
twist the screwdriver.

Do not insert the screwdriver too far and do not ap­ply excessive force to the lens, otherwise the bezel
surface may be damaged.

Operating Conditions

In corrosive gas or high-temperature, high­humidity environments, contact failure due to
corrosion or color change or breakage of the
housing may occur.

Main parts of the CW series switches are
made of plastic. Do not scratch the surface
with a sharp object or apply excessive electric
shock or load, otherwise the switches may be
damaged. In particular, keep the button, lens
and bezel from such damage, otherwise ap­pearance and function may be impaired.

Do not apply detergents, cutting oils, or
chemicals which may impair the function and
appearance of the CW series switches.

Panel Mounting

First remove the contact block and then the
locking ring from the operator. Insert the
operator into the panel cut-out from the front,
tighten the locking ring from the back, then
install the contact block to the operator.

Mounting Hole

1. Mounting hole dimensions are in compli­ance with IEC60947-5-1.

2. If the anti-rotation projection is removed
from the bezel, CW series switches can be
mounted in ø22.3mm mounting holes. To
remove the anti-rotation projection, remove
the gasket and use cutting pliers to break
the projection.

2. To install, align the TOP marking on the
operator with the TOP marking on the
contact block mounting adaptor, and turn
the locking lever to the right.

Installation in Panel Cut-out

Remove the locking ring from the operator.
With the anti-rotation projection on the opera­tor aligned with the recess in the mounting
hole, insert the operator into the mounting
hole. Tighten the locking ring from the rear of
the panel.

Note for Panel Mounting

When installing the operator in a panel cut­out, use the optional locking ring wrench
(MW9Z-T1) to tighten the locking ring to a
recommended tightening torque of 1.2 N·m. Do
not use pliers and do not tighten excessively,
otherwise the operator may be damaged.

Installing the Lens

Turn the groove in the lens to the TOP marking on
the operator housing. With the groove aligned with
the ridge, press the lens in.

identification. (Marking plates are not available for
CW series illuminated pushbuttons and pilot lights.)

positions.

Key Selector Switches

To prevent malfunction and damage, take the
following precautions.

Completely insert the key before turning.•
Do not remove the key while turning.•
Besides the standard key (0H), six other keys •

are available. Use only a key with a number
that matches the number on the switches’
key cylinder. (The standard key does not have
a key number.)

Keys are available in two shapes. •

-0H (standard), 1H, 2H: reversible keys

-3H, 4H, 5H, 6H: non-reversible keys
Make sure of correct insertion direction.

Contact Blocks and LED Modules

To remove the contact block from the operator,
insert a flat screwdriver under the latch and
push the screwdriver down as shown below.
Before removing the LED module, first remove
all contact blocks, and then remove the LED
module in the same manner.

Wiring

Applicable Wires

Stranded wire: 2.0 mm
Solid wire: ø1.6 mm maximum

One or two wires can be connected to the
terminal.

Applicable Crimping Terminals

Spade terminal
When using crimping terminals, be sure to use
insulating tubes or insulated crimping termi­nals.

Ferrule
When connecting two ferrules to one terminal,
use ferrules without insulation.

When using spade terminals or ferrules,
ensure that they are inserted completely.
Ring terminals cannot be used.

Screw Tightening Torque

Tighten the M3.5 terminal screws to a recom­mended torque of 1.0 to 1.3 N·m.
