If you wire a switch across a battery you will cause it to supply all the current it can. If that is a lot then yes it will blow up every time. I have difficulty believing that you do not know this. You need to do a lot more reading about circuits before doing any more practical work.
Then I see circuits with several components connecting to ground and several connections to positive, and I can't understand how it's working. It seems like it's no longer a circuit.
The relationship between the voltage and the current is given by ohms law, it is voltage divided by resistance equals resistance.
Hi, what sort of battery was it?
Sorry Mike, 2 out of 3 aint bad as they say.... He meant voltage divided by resistance equals current.
It is in fact several circuits all connected at the same time. This is known as connections in parallel. When the components are all in a single line from + to - this is known as "in series". Any none trivial circuit will have many current paths in series and in parallel.
