This is the Futaba SWH12 mini switch with 2 pin connector. This has the Hitec BEC style connector on it for the battery, which is similar to the connectors used in many RTR vehicles. It is also the same connector used on the VXR Racing Lithium Polymer battery packs, so if you wish to use the stock connector on your battery packs, you can use this switch to avoid having to rewire either the battery pack or your switch.
