Hi, I want to change one of my switches it looks to be a single way switch as it only has 2 brass terminals and connects to one ciling light but it has 3 wires and all 3 are red. 2 wires are twisted and go into the same terminal and one wire goes into the top terminal. it is hard to see as i can only pull the switch away by about 1 inch. so do i just undo this switch and swap them over. I have done loads of electrical work but am unsure about 3 red wires i know some have 2 red one black with red tape on but have never seen 3 red. any advice welcome. Thanks
