The switch has a small internal spring that tries to push the pin out. The pin when pushed in opens or breaks the circuit.If that pin does not work like that, and it does not take much spring force, than throw the switch away. Not normally rebuildable.

Does the pressure in the atmosphere increase or decrease?

Going farther up into air, pressure decreases. Going down, pressure increases. When you think about it, more air is pressing down on you when you are standing on earth because more is on top of you. When you are up in the air, there isn't as much air pressing on you which shows that there isn't as much pressure. The same concept applies when under water; The farther you go under, more water is pressing on you than when you are more towards the surface which=more pressure (underwater).
