Dual Use Switches allow for constant power flow to the USB charger, as such the switch function only controls the effective ‘split’ of the hub's power output between the front light and charging device. This means that the switch controls the front lights on/off function.
Dual-use switches are ideal for people doing long-distance races or tours who need to ensure devices are charged, an example of this is ultra-racing where you might need to keep a GPS tracked charged at all times as part of the race rules.

NOTE: Dual switches are identified by a ziptie on one of the conenctor cables

Single-use switch is the basic version, as it dictates where all of the hub's output is being directed, as such you can either have the headlight on, or the charging device on- but not both at the same time.
This is ideal if your touring, and not racing- as during the day you can charge all your devices with the full amount of energy the hub is providing, and at night have the brightest light.

Hub to Device:
Hub to device cables are pre-made lengths of cable, with an XT30 connector at one end, and either SON spade connectors at the other- or a Shimano style connector cap for use with Shutter Precision or Shimano hubs. These cables only allow you to connect a Klite headlight or a Klite charging device.
