switching device ...
Transistors which are refered to as 'switching devices' are really just
normal transistors, maybe not meant to have 'good' characteristics,
but still normal.
Its just a term,
they still turn on and off like ones that arent called switching types.
**********
In this particular case,
if the laser were partly obscured, like fog or smoke, or a fly in the way,
then it is quite possible that the transistor could be half open, or half
closed. Or in between.
But not likely enough to mention,
i only mention this to help you see that its just used as a current amplifier.
Hope that hasn't confused you at all.
I am most impressed with your level of comprehension so far.
Your questions are sensible, and show some understanding of a subject
which is very difficult for most people to grasp.
