• The above model is referring the 'A8GS-S1100'.
• No reset function models are without coil circuit.
• Specifications are same with reset function models.
Note: 1. Unless otherwise specified, a tolerance of ± 0.4 mm applies to all dimensions.
Note: 2. When initial operation or operation after reset, operating force is increased, due to switch structure.
Note: 3. TV-8 approved models are same outline and characteristics with standard models.
* Solder terminals model has different hole shape, compare with Quick-connect terminals. Outline and characteristics are same.

Precautions
WARNING
Do not wire the switch or touch any terminal of the
Switch while power is being supplied. Or it may result in
electric shock.
•Handling
• 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.
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.
Caution of usage
•Mounting
• 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.
Pushing position
Correct
Incorrect
•Environment for storage and use
• 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
(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.
• Strong magnetic field may cause malfunction.
Check function is recommended under practical use conditions.
•Using Micro Loads
•Wiring
• Confirm the size of the receptacles and be sure to connect them firmly.
• 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)
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.
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.
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)
• 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.
• In case of touching the soldering iron to the root of terminals, it may
cause Housing parts melt.
6
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
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
: 1,000 ppm max.
Mercury
: 1,000 ppm max.
Cadmium
: 100 ppm max.
Hexavalent chromium : 1,000 ppm max.
PBB
: 1,000 ppm max.
PBDE
