●Use the switch within the rated voltage and current ranges, otherwise the switch may have reduced durability, radiate heat, or burn out.
This particularly applies to the instantaneous voltages and currents when switching.

Correct Use


●Pay attention to the creepage distance/clearance distance for insulation after wiring onto terminal when mounting frame is made of metal.

●Wiring for switch

·Please use the receptacle that suits 4.8 × 0.8 mm quick connect terminal (#187) when using it as a quick connect terminal.
·Ensure that the wires are thick enough for the load (current) to be applied.
·The performance of the Switch may be affected if the Switch is used under micro loads. Test the Switch under the actual operating conditions.
It is possible to use the terminals as soldering terminal. But, it is not in compliance with safety standards for use as solder connection. Only the quick-connect terminals is in compliance with Safety standards.
·When soldering terminals manually, perform soldering within 5 s using a 60W soldering iron (temperature at the tip of the soldering iron: 360 degC max.). Do not apply excessive force to the terminals during soldering.
·Applying the tip of the soldering iron to the root side of the terminal can be a cause of deformation of the external portions that is the Housing and Base.
·This product doesn't correspond to the reflow solder and flow solder. It causes the malfunction by the infiltration of flux and the thermal deformation.

●Environment for Storage and Use

To prevent discoloration of the terminals and other problems during storage, do not store the switch in locations subject to the following conditions.
1. High temperatures or humidity
2. Corrosive gases
3. Direct sunlight
4. Sea wind
Also, the switch is not waterproof or splash-resistant. Do not install or use the switch in locations that are subject to contact with water.
Do not subject the switch to freezing or condensation.


When handling the product, any shock like drop should not be applied to it. Shock can cause break or deformation of the product.
Do not apply excessive operating force to the switch. Otherwise the switch may be damaged or deformed, and the switch mechanism may malfunction as a result. Apply an operating force not exceeding 30N {3,059 gf}. Do not apply a load from an angle or from the side of the actuator.

●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: 1,000 ppm max.
