This is a switch commonly used in fluorescent lighting fixtures for washbasins, under-cabinet lights, and similar applications. Please use it for DIY repairs, electronics projects, etc. Since there are multiple units, the item shipped may differ from the image. Therefore, there may be slight differences in the printing angle and color. Please understand this. Bulk purchases are welcome. Please write in the comment section if you wish to purchase in bulk. The app's bulk purchase function does not allow for a discount on shipping costs. Please note that repairs done by yourself are entirely at your own risk and require some knowledge and skill. I will not answer questions from those who ask "Can this be used for xx company's product?" without doing their own research, as they are not suited for self-repair. Please request repairs from the manufacturer. Manufacturer's website: http://www.shinden.com/rockerswitches/w103a139bbsp000.htm
