Dual Contact Closure
In dual pushbutton mode, each direction is controlled by the respective cont rol inputs. No wait states are
required to change wiper direction, balance, or volume in dual pushbutton mode. Additionally, in dual
pushbutton mode as the wiper position reaches the end of the potentiometer, the direction of wiper
movement will not change. Wiper position will remain at the potentiometers’ end until an opposite
direction input is given.
