Do not use the products with beyond the rated current and voltage. 10.3. Do not apply excessive load to the terminals and the operating part. 10.4. Larger static load than specified and/or shock shall not be applied to the operating part. 10.5. The stress shall be not applied to the upper face of the switch. 10.6. The switch will be broken, if you give larger stress than specified while operating. Take most care not to give both upward and downward stress to the switch when you operate it. 10.7. As the switch may be broken, please do no apply a load of more than 5N to the switch bosses. 10.8. After mounting the products on PWB/FPC, please do not stack too many PWB/FPC in order to avoid excessive load to the switch mounted area. 10.9. The dimensions of a pattern on PWB/FPC shall refer to the recommended dimensions in Product specifications. 10.10. Use of organic acid flux shall be avoided because it may cause corrosion of the switch. Please make sure the type of flux before you use it. 10.11. As this switch is designed for reflow soldering, if you place it at the edge of PWB for convenience, then flux may get into the sliding part of the switch during automatic dip soldering after being mounted, so do not apply auto dip after being mounted. 10.12. If the switch is given stress from the side, the cover may drop off and it may result in damages to switch functions. Therefore, please handle it with extreme care. 10.13. The operating part should be moved to the appointed position in order to ensure proper operation. 10.14. Do not give stress to the upper face of the switch while operating and use the switch under given stress. 10.15. If you use this product in one of the following environmental conditions, progress of sulfaration and oxidization on the contact part (silver) will be accelerated, which may cause contact failure. Therefore, be careful about the operation environment. 1) Around a sulfarate hot spring where sulfide gas is generated. 2) In case this product is always used in a place where exhaust gas from automobiles exist. 10.16. If you push the edge of the operating part, (refer to Fig.3) the switch might not operate properly. Therefore, pressure to the operating part shall be applied to the whole surface equally and avoid the pressured to the specific one portion. 10.17.
