This question was one of the common questions asked in the slightly recent phenomena called the "accent challenge," but it was the most interesting question to me... And the reason is that I've never seen anyone answer the way my parents and I refer to the device. My parents and I refer to this device as "the switch" like, "hey can you pass the [tv] switch" most of the time. So, where are you from, and what term do you use to refer to this device? (We're from central Illinois)
