Front Brake Switch? Won't start now.

So When I removed my mc for the first time I had no idea how everything went together and I think i accidently disassebled the entire brake switch instead of just unplugging it. I removed the metal band around the little rubber cover and unclipped it there. Inside was a small spring, a tiny metal cylinder, and a same size plastic cylinder, in addition to the rod that pokes out of the hole. Now I dont know how to put it together and when I tried the bike wont start and i cant even get the neutral light to come on. Anyone know how to put it back together so it works?
Also, the reason I took it off was to rebuild the mc, and after doing so and attempting to bleed the brakes, the lever is really stiff and the brakes are locked up. what does this mean?
