Automatic transmission switch

The utility model relates to an automatic transfer switch, a power management system for circuits of families, apartments, facilities and buildings comprises a power grid interaction system, and the power grid interaction system comprises a flexible wire, an electric connection to a socket and a connection to an external power generation device. Embodiments include an automatic transfer switch for securely transferring a power source for an electrical circuit from a primary power supply to a power generation device. The automatic transfer switch may include a microcontroller, a current regulator, a relay, and circuitry, where the switch is configured to prevent power from the primary power supply from propagating back into the secondary power supply. In addition, the system may include a communication interface or an automatic interface associated with a system that detects a power failure or other grid or time related event. 本实用新型涉及自动传送开关，用于家庭、公寓、设施和建筑物电路的电力管理系统包括电网交互系统，该电网交互系统包括软线、到插口的电连接以及到外部电力产生装置的连接。实施方式
