What type of connector is this? Looks like two pins but is only one

It's a special switched connector for testing or using external antennas. Notice that there is a trace on both sides of the connector, but only one side on the u.fl connector. When you plug a test connector into the jack, it actually disconnects the signal flowing through it and routes it out the test connector instead. They show up all the time in wireless routers and the like because they can be used to perform accurate tests on the radio with the antenna disconnected before it ships. They can also be used to add an external antenna to a device by bypassing the internal antenna. This is one series of this type of connector:

It looks like the connector is part of the Molex PicoFlex surface mount series. All connector headers, housings, and mates can be found here.

The only thing I see in the pictures is the blade pins aren't staggered, but that just might be laziness by molex. I looked through all "blade pin" style connectors on digikey and this is the only match I could see.
