Not to worry -- there ae no stupid questions. The most common problem with newcomers, IMO, is that they overthink things and make it harder than it needs to be.
If you're happy with MichaelE's answer, OK. I'm still not sure what you're trying to achieve. By "switch", I'm guessing you mean the button or switch that will tell the turnout motor tp actually move the points. And you're thinking that you actually want these switches physically on the layout, right next to the turnout that they operate? While this is, of course, a possibility, most people would want to avoid having to stick their large 1:1 scale fingers into a yard ladder to hit that switch. The possibility of an errant finger, hand, sleeve, etc. knocking something over or derailing it is pretty huge. For this reason, most modelers locate the activation switch and the indicator lights at a remote location, either at the edge of the layout (the fascia) or at a more distant location on a dispatchers panel with a track diagram. Here is an example of such a panel made by my 12 year old son:
