Look my colored picture , between bright red and dark red is switch S1.
If you follow line from R3 it goes to IC-pin 4, IC-pin 8, R1 and S1 right pin. (Bright red)
S1 breaks to line to battery plus. S1 left pin goes to plus pin. (Dark red)
What you describe is electrically exactly the sane thing.It's not clear to me on this schematic whether D1 is connected from pin 3 then to R3 then R3 to positive , or whether D1 is connected from pin 3 then to R3 then R3 to pin 4 which is connected to positive. ...
In other words are D1 and R3 connected to pin 4 or straight to positive?
You can't. A diagram shows how the components are connected electrically, not physically.And how can i tell just by looking at the schematic?
