Bathroom light switch faulty
Bathroom light switch (2 toggles) operates two lights. 1 bank of lights gone out. Opened switch, found 2 cables coming in, 1 with a red and earth and the 2nd with a red and black.The first cable has the earth properly earthed and the red going to A1. The second cable has a red going to A, and the black was loose! A and B are joined by a small red cable. I presume the black should go to B1, as 1 bank of lights work like this, but the other doesnt.
