Double power switch is a device that is controlled by microprocessors, which can be used to switch the power supply of the power supply from the power source of the power grid system. Series double power, when power failure or power failure suddenly, commonly used by double the power switch, automatic into standby power, standby power (small load can also be used by the generator power supply) make the equipment can run normally. The most common ones are elevator, fire control, monitoring, lighting, etc.

This project focuses on innovation points in the rationality of user operation and the integrity of appearance. Compared with the first generation, the product not only improved the process quality, but also optimized the user experience and reduced the error operation.

In the first year after the project was released, market sales increased by about 30% compared with those in the early days. It has been in the domestic market and has been trying to expand overseas through this product.

This kind of power conversion system is a combination of switch and logic control, without the need of a controller, the automatic switching switch of electromechanical integration is realized. The contact system of this kind of power switching system adopts the design of "single pole double throw", which is designed and manufactured for uniform design, with small volume and simple structure. This product does not have the current protection function, belongs to the PC class switch switch electrical products. The product conversion time is generally small, switch drive motor drive, stable switch operator motor drive only in the switch moment is energized, do not need to provide the working current when the steady state, energy saving is obvious. The product has no temperature rise heating, contact point bonding, coil burning phenomenon. Switch with mechanical and electrical interlocking device, which can realize the vote since the complex, since the vote from the complex, pressure loss, undervoltage, phase failure protection, manual - automatic conversion, time delay control, switching power supply for the mainstream products.

Hangzhou han degree of industrial design co., LTD. Is a strategic vision of the original industrial design strength, is located in the design of atmospheric "creative garden", is a young, passionate design team. With professional design research, passionate creativity, rich industry resources and excellent execution, handu creates more and more value for customers.

The original intention of this project is to improve the design of first-generation products, not only the total innovation of appearance, but also the improvement of structure and operation mode. This product in the company to establish perfect marketing system, implement the "brand marketing and network marketing" phase on the development strategy of the whole provides strong basis, provide the support for the products sell well all over the world, and for many key projects to choose.
