The switch, however, is more. It requires the top to be popped off a bit before the side panel will come off. Even if you undo the side screws, you also have to undo the main body screws too. Its a bit of a job.
The plastic slider is held in a plastic track and uses a spring to slide it across. If the unit was put together without care there is a very small plastic casting tab that breaks and can get caught in the plastic track, stopping it from opening.
If its a warranty issue, send it back, get a refund or ask for an exchange.
