This might be a dumb question but I'm unable to understand:
When we create a new branch, why do we need to 'switch'? What does this 'switch' exactly do? Can't I use the whole repository as I was using earlier without bothering about switch?

Using switch will update your working copy to use the new branch you just created.
As an example, if you create a branch from your trunk, you will probably want to switch your working copy over to the branch you just created so that you can make edits, etc.
Switch changes the association between your working copy and the path on the server. You can branch from your working copy from trunk (for maintenance) and continue hacking away - still on trunk.
