break in a case with return.. and for default

If I have a switch statement:

switch()
{
    case 1: ...
    case 2: ...
    ...
    default:
        break;
}

Is there any reason for the break in the default clause? I see this in quite a few places, but isn't it unnecessary? What is the general practice?

Can another case label come after the default clause?
