将负载返回换接至常用电源（兼断相保护功能）。
 ◎开关可能根据用户要求设置电源下降时切换电压范围。
技术参数 ●开关控制器工作电压为AC220V。 ●开关机械寿命(N-R-N循环)为5000次。 
●最小转换动作时间为1.5~4S。 ●开关具有失压、欠压、过压、断相、延时、启动油机、消防、
自投不自复、备用优先、切换功能。 ●开关随机携带操作手柄、作为应急手动操作开关之用。
（在断电情况下使用） ●具有三种稳定工作状态：状态Ⅰ：常用电源合，备用电源合，
状态Ⅱ：常用电源分，备用电源合； ●状态Ⅲ：常用电源分，备用电源分。
正常工作条件

The load is transferred from a common power supply to a standby power supply,
Change the load back to the common power supply (and phase protection).
The switch may be set according to user requirements of power down when the switching voltage range.
The working voltage of the switch controller is AC220V. Switch mechanical life (N-R-N cycle) for 5000 times.
Minimum conversion b time is 1.5~4S. Switch with pressure, under voltage, overvoltage, phase failure, delay, start the engine, fire,
Since the b is not self recovery, standby priority, switching function. Use the switch to operate the handle as an emergency manual switch.
(in the case of power failure) with three stable working state: state I: common power supply, standby power supply,
State II: commonly used power points, standby power supply; state III: common power points, spare power points.
