Review on Optimized Mounting Position for Baomain Changeover Terminals by Desmin Dickerson

This switch replaced a 30 year old German model on my Grand Banks. A new derailleur costs less than 10% of the cost of a new exact replacement model. Yes, the instructions are in Chinese (a downside), but if you can't figure out which wires connect to which position, you may not need to install this yourself. It took me about 10 minutes to figure it out. The bezel was the perfect replacement for my old switch, so that was perfect too. It feels comfortable and works for a few months without any problems. I expect good long-term results. I used a switch to connect three battery voltage inputs to a meter output. I had to add a jumper to get the exact functionality I needed for 3 to 1, but that was easy to figure out. Buy one for the price and find out!
