There is no trip, the lamp and the socket are dead, but there is an LED light (not lit) with weak light. It's normal to pull the brakes and push them up. What's going on here?

Maybe there is something wrong with the quality of your main air switch. The reason is that your ironing machine consumes a lot of electricity. After plugging in, the current suddenly increases, resulting in poor contact of the internal contacts of the air switch and power failure (the air switch will not "trip" at this time).

When you pull it down and close it again, it may be because of external force that the contacts in the air switch are closed again, so the power supply is turned on again. No, change the air switch.

See where the air switch is made. The quality of many Zhejiang goods on the market now is very poor!

According to your supplementary information, there should be something wrong with your main air switch (or the air switch near the electricity meter before entering the house), or the abnormal power failure caused by the loose terminal of the main switch. I repaired the same phenomenon for a relative's house, which was caused by loose screws and poor contact of the open terminal above the aisle electric meter.

You should go and see the electrician of the property management staff. Summer is coming, and electricity consumption will go up a lot. Maybe this fault will keep happening. Fix it quickly.
