Problems solved by technology
[0002] In daily life, it is inevitable that the air switch will accidentally trip. Once a trip occurs, the users on the lower floors are fine, but the users on the higher floors can only go downstairs and turn on the switch again to restore the power. Once infected with wind and cold, it will lead to unexpected situations such as sickness and inability to go to work, which will cause economic losses
