I know this is a banana plug [connector A]: http://www.muellerelectric.com/images/BU00249LG.jpg But what type of connector is this [connector B]: http://www.vhaudio.com/images/wbt-0600.jpg Note that in [connector B], the plug is a shaft split into a (+). Could also have been split like a (-). These are 4mm plugs that fit into standard banana sockets. I have a few of these (the (-) style) and they are far more rugged than [connector A]. They are easily bendable when the spring action weakens, or to increase the grip friction in the socket. I want to buy more of this type, but have no idea what they're called. Searching "banana plug" yields [connector A]. What type of connector is this? --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
