it's for the voltage coming out of your wall socket. you have to either set it for 115, or 240 volts. The US uses a standard of 120 volts at the wall socket. Europe uses 240 volts at the socket, and a different power cord.

it's the power swithch with a rating of 115 volts. it may also be the reset switch if you have a power surge that causes the unit to shut down. and on some, it is the power breaker if an overload occurs. to reset it you have to push it in, or flip it to the other side. the particular use would be described in the user guide or instruction manual, or paper, if it has one.

The red switch on your power supply allows you to select the voltage you will be using. Here in the USA we us 115VAC. Over seas like in England they use 230VAC.
The switch it self changes the windings on a transformer that reduces the voltage from the wall to what is used in your computer.

Without know exactly what your have, I would have to say that is a breaker switch which is rated for 115 volts.

its a voltage thing, some areas in the world (forgot exactly) have slightly different standard voltage comming out of their wall sockets, you need to know which is comming out of your socket or your computer won't turn on because the psu is expecting one voltage and getting another (not sure if voltage is the right term, but its something along those lines)

Do not change it you will burn the power supply, this is to be used in deferment countries there power system is deferment from ours.
