You don't say what your application is, apart from being underwater, but could you make your own switch? A Perspex disc with a piece of fridge magnet mounted in it, with suitable method of detenting, mounted outside the waterproof case, operating a reed switch or hall effect device inside the waterproof case. Would allow you to have your own detent size - greater than the normal 30 degrees if you wish. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
