Why is my iPod Classic turning off when on hold?

I recently got an iPod 6th generation at 160 GB and it works fine. Works like a charm. Except that whenever I flick the hold switch, it doesn’t just keep the controls on hold. It automatically just turns off my iPod completely. When I take it off hold, it resets my iPod to the apple logo. So the hold switch how I see it does work but not what it’s supposed to do. It’s basically a kill switch more than a hold switch so I wanna know what should I do with this malfunctioning hold switch if there is any fix or I have to completely get a replacement of some sort.
