description: It is the invisible programmable devices under the user's fingers that make handheld devices so convenient and fun. These handheld devices are equipped with a battery capacity that is sufficient for a child's concentration period or an adult working day, so that as long as the battery has a chance to recharge it, people can enjoy it again and again. Chargers in some of the more advanced devices have powerful programmability, which not only shortens the charging cycle, but also extends battery life. See the PDF document for details.
25MM Metal Switches
25MM Metal Switches are fashion in appearance and excellent in quality with IP67 dust-proof and waterproof grade. The Power start control system has always enjoy the sound reputation in the long-term international transaction. 25MM mounting hole metal Anti-Vandal Switch could equip with LED light, it can be two-color LED light bead, such as red and green, or red and blue color.
This series Metal Push Button Switch has obtained relevant quality certifications in Europe and the United States, and can be used for dust-proof, oil-proof and waterproof stains in harsh working environments. All the material has passed the strict customs declaration to ensure that this metal switches could meets the requirements of green environmental protection in Europe and America. REACH contains Substances High Concern SVHS, also could offer our customers PPAP reports. We are paying very close attention to Green environmental protection project, which is not only our requirements on products, but also our company's attitude towards the international environmental project.

Nowadays, the development of charger programmability has far exceeded the above two basic requirements of handheld devices. While monitoring the charging voltage and current, the charger can also monitor the battery temperature at any time to accurately control the battery charging speed. This results in optimal battery capacity recovery and safety. The charger also continuously monitors the battery voltage during battery use, not only to alert when the battery voltage is low, but also to tell the user the remaining time that can be used before the battery must be recharged.
This programmability is primarily implemented in an integrated circuit of a battery charger located within the device. The charger can communicate some of the information it obtains with a semi-dedicated microprocessor that manages the operation of the device, shutting down unused or idle portions of the system. , thus effectively extending battery life.
