Safety Precautions

Be sure to read the Safety precautions common to all PCB-mount Manual Switch for correct use.


Use the switch within the rated voltage and current ranges, otherwise the Switch may have a shortened life expectancy, radiate heat,or burn out. This particularly applies to the instantaneous voltages and currents when switching.


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 9.8N {1,000gf}. Apply the operating load from the top of the actuator. Do not apply a load from angle or from side the actuator. Doing so may deform the Switch contact.


Observe the following conditions when soldering the Switch.
·Automatic Soldering Bath
Soldering temperature: 260 ℃ max. (Preheating: 100 ℃ 120s max.) Soldering time: 5s max.
· Manual Soldering
Soldering temperature: 350 ℃ at the tip of the soldering iron. Soldering time: 3s max.


Apply alcohol based solvents to clean.
Do not clean the Switch immediately after soldering. Wait for at least five minutes after soldering before cleaning.
Ultrasonic cleaning is not available dip into Switch washing agents for two minutes maximum.

●Using Flux

Making mistakes in the type of flux or in the amount or method in which it is applied can cause flux to enter the interior of the Switch, with adverse effects on Switch performance. Assess the proper flux, conditions,and methods prior to using it.

●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.
PBDF:1,000 ppm max.

●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 temperature or humidity
2. Corrosive gases
3. Direct sunlight
Also, the Switch is not waterproof or splash-resistance.
Do not use the Switch in locations that are subject to contact with water. Do not subject the Switch to freezing or condensation.
