That's the way my brain sees it too. I am wondering though, whether the=20 contacts are sprung and close the circuit when the plug is connected. It looks as though the pins on the appliance might possibly push the=20 contacts a little way in. I can't quite believe they would design a magnetic plug for safety=20 purposes in one area and overlook another. Although maybe the photo=20 makes the contacts look nearer and more accessible than they really are. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
