Nigel Riches Posted March 22, 2015 Share Posted March 22, 2015 Hi Kingsley, from my search on the interweb the thread is 1/8 NPT. Have a search for "bmc mini brake light switch", the same switch is found on several different makes and models. Nigel. Link to comment Share on other sites More sharing options...

Area Representative Kingsley Young Posted March 22, 2015 Author Area Representative Share Posted March 22, 2015 Hi Nigel I have looked into the Mini brake switch, when I was at the Classic Car show in November I bought a switch from one of the stalls and as its turned out is the Lucas SMB 423 which is the one that fits the Mini. This I was told would be the one I needed , but alas it is not !! They look the same but are not. The threads are different, so I have been onto the Caterham site and ordered one from them. Thanks again for youn input. Kingsley. Link to comment Share on other sites More sharing options...
