MOG - it's a bit like watching paint dry! Just like my MSc - the whole 2 years could have been condensed into about 6 months... but with no time in the student bar, of course.
+Zeamus634 - This is called an intermediate circuit. So its like having a Light Switch Downstairs, a Light Switch on the Landing (Upstairs) and a Light Switch Half Way. He took the Live to the furthest point then looped back towards the Light. It wouldn't work in reverse if it looped in through the light first (straight from the CB) as it would be permanently illuminated.
