Hi, I can say my switch does not rotate. There is nothing wrong with any of the seat controls, when the seat is at its optimum height and adjusted to my leg length the seat is to low at the rear! It would appear I am just going to have to live with it. thanks for everybody's input. Paneuro.

 

I thought you meant it is fine until you adjust the leg length and then it lowers at the rear. When I adjust my leg length, the rear height stays exactly the same.

 

Yes, what you say is correct and mine does exactly that. The controls all work as they should. What I was looking for was some way to bring the seat up further than the standard optimum height at the rear. thanks Paneuro
