Safety Precautions
Refer to Safety Precautions for All Pushbutton Switches/Indicators.
•Never perform wiring work on a Switch while power is being
supplied. Never touch terminals and other charged parts while
power is being supplied. Doing so may result in electrical shock.
•Never attempt to disassemble or modify the Switch in any way.
Doing so may prevent correct operation.
•Switch functionality may be inhibited. Do not drop the Switch.
Never apply a force that would deform or alter the nature of the
Switch.
•The durability of the Switch is greatly affected by operating
conditions. Evaluate the Switch under actual working conditions
before permanent installation and use the Switch within a number
of switching operations that will not adversely affect the Switch’s
performance.
•Do not use a load voltage or current that exceeds the rating. Doing
so may damage or cause burning in the Switch.
•Do not use the Switch in a location with inflammable or explosive
gases, or where the Switch would be subjected to inflammable
solvents. The arcs and heat generated when the Switch is
operated can cause ignition or explosions.
•Do not use the Switch where sulfur gas (H2S, SO2), ammonia gas
(NH3), nitric acid gas (HNO3), chlorine gas (Cl2), or other harmful
gases are present or where high humidity is present. Contact faults
and damage due to corrosion may interfere with the functionality of
the Switch.
•Do not use the Switch in oil or water or in an environment subject
to constant contact with oil or water. The oil or water may enter the
Switch, causing failure.
•Do not use or store the Switch in the following locations.
•Locations subject to rapid temperature changes
•Locations subject to condensation due to high humidity
•Locations subject to vibration
•Locations subject to direct sunlight
•Locations subject to salty air
•Make sure that the rubber washer is in place between the
Operation Unit and the panel. Otherwise, the specifications of the
protective structure may not be satisfied.
•Do not subject the Contact Block or wiring to excessive force. The
Contact Block may be damaged or deformed and faulty contact
may occur.
Mounting
•Do not tighten the Mounting Nut more than necessary using tools
such as pointed-nose pliers. Doing so will damage the Mounting
Nut. (The tightening torque of the Mounting Nut is 1.0 to 2.0 N·m.)
Wiring
•Terminal screws must be M3.5 Phillips or slotted screws with a
square washer.
•The terminal screw tightening torque is 1.0 to 1.3 N·m.
•Solid wires, stranded wires, and crimp terminals can be connected
to the Switch.
Stranded wires: AWG14 to AWG16
Solid wire: 1.6 dia. max.
Bare Crimp Terminals
Crimp Terminals with Insulating Sheathes
•After wiring the Switch, maintain appropriate clearance and
creepage distances.
Operating Environment
•The Switch is intended for indoor use only.
Using the Switch outdoors will result in failure.
LED Lamps
•A current-limiting resistor is built into the LED Lamp, so external
resistance is not required.
•False Lighting of the LED Lamp
The LED Lamp will light with a microcurrent of approx. 0.1 mA or
less. Take countermeasures, such as adding a resistor in parallel
to the LED Lamp, to prevent false lighting.
The micro-current varies with the machine (due to leakage current,
stray capacity between cables, etc.). Select a resistance value and
allowable power consumption according to the actual current.

Application
Mounting to the Panel
Panel Hole Dimensions
•Panel hole dimensions are given below.
•The recommended panel thicknesses are given below.
•If outer surface treatment such as coating is performed for the
panel, the panel dimensions after outer surface treatment must
meet the specified panel dimensions.
•The following figure gives pitch dimension A and pitch dimension
B between the centers of the mounting holes.
Dimension A
Note: The minimum mounting pitch is based on three Contact Blocks
in stage 1 with one wire attached to each terminal.
If you attach two wires or link Units, determine the mounting
pitch based on the dimensions diagrams and ease of operation
and wiring.
Dimension A When Using Accessory
•Dimension A is 50 mm minimum when a Standard Legend Plate
Frame is attached.
•Dimension A is 51 mm minimum when a Large Legend Plate
Frame is attached.
•Dimension A is 75 mm minimum when a Protective Cover is
attached.
Dimension B
Mounting the Operation Unit
•Panel Hole of 22.3-mm Diameter
Insert the Operation Unit from the front of the panel, insert the Lock
Ring and Mounting Nut from the back of the panel, and tighten the
Mounting Nut. Before tightening, check that the rubber washer is
present between the Operation Unit and the panel.
•Panel Hole of 25.5-mm Diameter
Do not use the Lock Ring, and tighten the Mounting Nut while
confirming that the projecting part (see following figure) on the
Mounting Nut is aligned with mounting hole. Before tightening,
check that the rubber washer is present between the Operation
Unit and the panel.
•Align the Lock Ring with the slot on the case and insert it so that
the edge is flush with the panel.
Mounting the Contact Block to the Operation Unit
•Insert the Operation Unit into the Mounting Collar, aligning the TOP
mark inscribed on the Operation Unit with the lever on the
Mounting Collar, and then turn the lever in the direction indicated
by the arrow in the following figure all of the way until it clicks into
place.
