Zvilnik red vs blue

It's you and me, puzzle to solve
A detonator
Select a wire, just make a choice
And see what happens
One stops the clock, one sets me off
This should be simple
So take a chance, just take a shot
And see what happens
If you push me
I might explode
But don't you see, if I explode
I serve my purpose
But maybe I don't want to die
But then what good am I?
So cut the red, or cut the blue
It makes no difference
Which one you choose, I'm bound to lose
So see what happens
If you push me
I might explode
