What happens when you press this small button in the subway car?

Addendum 1:

Another little piece of knowledge for showing off in front of friends and family has been added~

Addendum 2:

There is also one thing on an airplane that you must never touch: the emergency door.

If you activate the emergency door switch without authorization, you will be "praised" by all the crew members, and the first thing they will do after the emergency landing is to arrest you and detain you, usually for 10-15 days.

Addendum 3:

If the emergency door you open happens to be equipped with an emergency slide, there will be huge compensation waiting for you, starting at 50,000.

If the plane is stranded because of you, you will also be responsible for the rebooking fees, food and accommodation fees of other passengers on the plane, as well as the fees incurred by the airline to dispatch other flights. It is almost hundreds of thousands of yuan. It is recommended that the old man who does not have a mine at home should not touch the emergency door.

Addendum 4:
