Typically the antenna booster switch is not only a way to turn the booster on/off (located in the antenna by the way) but it is also an electronic switch that selects between the antenna and cable.
I'm surprised the cable connection (from outside) does not go directly to the wall plate booster/amplifier so that when you turn it either off or on, it selects between antenna and cable.
