Problem: Brake lights won't turn on

I have checked 2 things, fuse + bulbs. Both are still good, so I am thinking it is the switch underneath. Does anything look wrong from the pic? Which one is the brake switch and what is the other one?

Is there anything else that could be causing my brake lights to fail? I could only think of these three things unless theres something wrong with wiring(i hope not).

Hope this helps:
