Property maintenance power grid. Why did my front door trip?

1 The air switch is small, and two household appliances are leaking electricity. Try one household appliance at a time to see the schedule, and then change to another model or the same model as the previous air switch, but not smaller than the previous one. Now let's see if it's related. Do you think this switch can cut off the power supply? Is there still electricity in the place it controls after the gate is closed? Let's see if this switch can trip automatically now.
