OK, just a little learning here. You need to get a little handle on some switch terminology. A simple switch with 3 terminals really doesn't say much about the switch configuration. The switch you would want would be a DPDT (Double Pole Double Throw) as shown in the attached image. The switch has two positions to select either the battery or the adapter as a source for your device. The fact it has six terminals is really here nor there as many types of switches could have six terminals. As drawn the switch is ON - ON with no OFF center position so either on or the other is always selected. Now is that what you had in mind?

<EDIT> Yes, in the drawing Adapter is not spelled correctly! </EDIT>
