Jan:when you look at the various types of plug and sockets in different countries,most design have basic layout that’s existed for decades in terms of the way the pins are laid out and the profile of pins.and manufactures the postion of our company has always been basically to accept that we are stuck with several standard configuration and effectively say to customers ,we produce all the main format takeormat whichever one you want.however as I am sure you know many countries use plugs and sockets of more than one format.and this leads to a comparative situation, with some configuration becoming more popular ,and other progressively being abandoned . this is particularly true in countries undergoing rapid economic expansion .and because of this process of selection . we are finding that big customers are increasingly asking which of the standard plug and socket formats in current use we recommend as a manufacture which are the best from a technical standpoint ? up until now we have not had standardized company policy that allows us to say these are the configurations we recommend ,and thses are technical reasons why are recommend them.
