I've had this 80's electric shifting crankset for a few years, and am trying to get it up and running for a new project.
It was licensed by Suntour from the Browning company who invented it in the 70's, and then marketed as BEAST (Browning Electronic AccuShift Transmission) in the 80s.
Trouble is, although they work, the buttons you use to change gear have suffered in storage.
Getting original spares is nigh-on impossible, but I'm thinking it can't be too hard to replace the buttons with a handlebar mounted, er replacement; and you can get motorbike/scooter/mobility vehicle switches. But my electronic skills are dire.
From the pic, and your skill and judgement, can anyone tell me what I need in terms of a replacement switch?
When you press 'H' it sends the solenoid one way; then (I think) the movement of the crank re-centres it; once centred, when you press 'L', it sends the solenoid in the other direction.
I've seen neat motorbike two-button switches, but these require a relay (which does I'm not sure what).
Any advice/links to suitable switches appreciated.
