People react differently but being knocked unconscious I'd say was... impossible unless you did something really stupid and got the voltage across your brain which would require significant effort to do so.
The way a stun gun works is it locks up your muscles by spamming them with electrical pulses causing them to contract. There is the potential for that to happen however this is a much lower power device than your average stun gun and the effect, should it happen at all, should be much less, more painful than incapacitating.
The key thing is to never have a scenario where you are in contact with the high voltage AND unable to turn the circuit off.
The switch you can see on the white boxed circuit is:
1) Insulated - it's made of rubber on a plastic box. Pressing the switch cannot result in contact with electricity.
2) Momentary - press down firmly, the circuit is live, let go and it's off. The circuit will not stay on without you holding the button down.
In the scenario you give there is no reason whatsoever for you to be wiring up a circuit that is attached to a battery.
That's extremely dangerous especially if you are not 100% on how it works.
All switches should be off and battery removed before you do anything with it.
The capacitor on the circuit may hold a charge of a few hundred volts and could shock you once if you don't short it out or add a resistor to drain it when power is removed but aside from that the circuit is safe to fiddle with.
