Operation
Delay OFF Function
Power contacts are kept in ON status, even if button is operated to turn OFF by manual operation of button.
And Switch is turned OFF by external signal to coil embedded in switch.
(1) Signal contact terminal and Power contact terminal are turned ON by manual operation of button.
(2) Power contact terminal is kept in ON status, even if button is operated to turn OFF by manual operation.
Only Signal contact terminal is turned OFF.
(3) Power contact terminal is turned OFF when external signal is applied to coil.
Furthermore, it is able to turn OFF both signal and power contact terminals from manual ON condition at the same time by
applying voltage to coil as Remote Reset Function.

Note: 1. Unless otherwise specified, a tolerance of ± 0.4 mm applies to all dimensions.
Note: 2. At initial operation or operation after reset, operating force is increased, due to switch structure.
Note: 3. Solder terminals model has different hole shape, comparing with Quick-connect terminals. Outline and characteristics are same.
Note: 4. No models of switch without delay off function (without coil), due to product design.

Precautions
•Handling
WARNING
• Do not apply excessive operating force to the switch.
• Do not drop or apply the excessive shock.
Otherwise the switch may be damaged or deformed.
• Do not impose force to operating part from an angle, Otherwise the
switch may be damaged or deformed.
Do not wire the switch or touch any terminal of the
Switch while power is being supplied. Or it may result in
electric shock.
Cautions
Use the switch within the rated voltage and current ranges, otherwise
the switch may have deteriorated durability radiate heat, or burn out.
This particularly applies to the instantaneous voltages and currents
when switching.
Correct
Incorrect
Caution of usage
•Environment for storage and use
•Mounting
• To prevent the terminals color change and others while storage,
Do not keep for a long term in the following conditions.
(1) High temperature, high humid environment
(2) Corrosive gas
• Easy to mount by snap fitting.
• Do not impose excessive force on switch at the time of panel
mounting.
• Do not detach the switch after installed. Otherwise, the holding
strength may be loose.
• Apply the force to housing when installing to panel. Do not apply
the force to the button (rocker) part when installing to the panel.
(3) The place where the direct rays of the sun
(4) The place where the sea breeze
(5) Environmental with a sudden temperature change
This switch is not sealed to prevent from entering dust and
liquid.Do not use under dust and liquid condition.
• Switch shall not be icing or condensation.
Pushing position
• Strong magnetic field may cause malfunction.
Check function is recommended under practical use conditions.
•Using Micro Loads
In case of using the switch under the micro loads, please refer the
Minimum applicable load and set the load more than minimum
applicable load.
•Wiring
• Confirm the size of the receptacles and be sure to connect them
firmly.
Even when using micro load within the operating range, if inrush
current occurs, it may increase contact wear and so deteriorate
durability.Therefore, insert a contact protection circuit where
necessary.
• Use an appropriate wire allowable to carry current.
• Be sure that there is no mechanical stress on terminals and coil
terminals.Otherwise, the switch may malfunction and/or damaged.
(Example: Too strong wiring)
The minimum applicable load is the L-level reference value.
This value indicates the malfunction reference level for the
reliability level of 60 %. (λ±60)
The equation, λ 60 = 0.5 x 10-6 /operations indicates that the
estimated malfunction rate is less than 1/2,000,000 operations with
a reliability level of 60 %.
•RoHS Compliant
• Take appropriate insulation distance between switch terminal and
other metal parts after wiring.
• Coil has polarity, please confirm polarity when wiring.
• Do not apply continuous voltage more than 10 seconds at any
time. Otherwise, insulation deterioration may occur by heat of coil.
Please consider the circuit design.
• Reverse voltage may cause of accurate discrete semiconductor
devices. In case of controlling by accurate discrete semiconductor
devices, Please consider the circuit design. (Example : add the
surge absorbing circuit)
• In case of manual soldering, soldering time is max 4 sec by
soldering iron (Max 350 °C at the iron tip) and do not add the stress
to terminals.
The "RoHS Compliant" designation indicates that the listed models
do not contain the six hazardous substances covered by the RoHS
Directive.
Reference: The following standards are used to determine
compliance for the six substances.
Lead
Mercury
Cadmium
Hexavalent chromium : 1,000 ppm max.
PBB
PBDE
: 1,000 ppm max.
: 1,000 ppm max.
: 100 ppm max.
: 1,000 ppm max.
: 1,000 ppm max.
• In case of touching the soldering iron to the root of terminals, it may
cause Housing parts melt.
