I have found, and made a working model of a lever which is positioned between two springs. The lever is two parts, one that is greater than one to one, and one that is one to one which. The two remain constant in position to each other throughout the movement. I now have the design for the switch. So, what I am saying is when switched one way, the one spring compresses the other and when switched to the second position, the two springs are equal which drives the lever back to the starting position. I am asking because I am at the point of asking if anyone here is involved in this research and development. Thank-you.
