  Hello, I'm Sandstein. I wanted to let you know that I removed an external link you added to the page Membrane switch, because to me it seemed inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page, or take a look at our guidelines about links. Thank you.  Sandstein  10:34, 6 September 2012 (UTC)Reply

  Please stop adding inappropriate external links to Wikipedia, as you did to Electric motor. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Because Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings. If you continue spamming, you may be blocked from editing Wikipedia.
