Where can I find more information of what protocol Shimano di2 uses to change gears I would like to add an additional switch so I can change gears at the different hand position

bluetooth

I dont think so - its not wireless

http://www.competitivecyclist.com/sh...-wireless-unit

According to the blurb at that link, the Bluetooth permits the derailleur to send information like cadence to the head unit. It says nothing about two-way communication, such as sending commands wirelessly to the derailleur.. What the OP wants to do is to send commands to the derailleur.

Electronic chatter is not necessarily a symptom of intelligence

Similarly, the rigidly consistent taking of chatter at face value does not necessarily reveal a lack thereof.

Does the switch wiring use silicone wires ?

I made a pun on the Shimano acronym Di2, Doug. That's *exactly* not taking chatter at face value, the very opposite in fact.

So what are you on about?

Any event, I wasn't speaking to you, I was speaking past you, as indicated by putting the crack in the tagline to my sig. Come to think of it, Di2 itself contains a further pun, but I'll leave Shimano to explain to you.
