The 'old' Pro Pedals are supposed to work in games that support toe brakes, all though I do not know which ones. No, you don't have to 'throw' the switch, it is for changing from rudder control to brake/accelerator car control. Have you tried plugging in the second plug into a game port? I believe you have to have at least 2 gameports and plug in the second plug at the end of the cord to get the toe brakes to work as toe brakes, otherwise they are just brake/accelarator pedals when the switch is used. There is some info on them on CH's webpage or in the Pro Pedal Help files, I can't remember where I have seen it.
