thanks friend ,,
but i m still not getting right thing,,
let i explain it what exactly i m thinking...
There is one handle (or u can say regulator),it have 5 fixed position to move and default position is 0,then that handle we can manually move from 0,then 1 to 5,,at these position of handle the value are giving to single indicator is 0, and when that handle is again move from its 5th position to 1st position then values for that indicator are changes as 100 for 5th to 2nd position and at the 1st position it shows 60..
and for this system i cant use button to reverse that sequence because that handle is move to different position from user,
