Sorry I just had to do this.

That light travels like a bullet in a straight line, so the light that left the star shot out and just arrived on earth, so we could "see" it.... Even though the star (gun) is gone, the light still travels......

Is this also what happens to the light when you turn off the light switch?

Yes, but on a smaller scale... We could test the theory, if we could afford a replacement light switch for the one at the end of the tunnel
