Managed to locate a new switch eventually...Went down to Marks and spoke with his knowledgeable techs....The one from his parted LAH was no good....
My local electrical shop had the perfect switch - a 4 post DP/ST 250v 15amp switch...Once I opened the packet the switch has on it 20a so perfect swap...All in and working good. 
Great stuff - Too easy.
Marks Techs are A1.
