Abstract
A motorized window covering switching mechanism is described herein. The switching mechanism includes a deflectable arm and a pull cord. The deflectable arm is connected to a first contact, and the pull cord is connected to the deflectable arm such that, as the pull cord is tugged, the deflectable arm deflects to move the first contact toward a second contact, thereby converting gestures of the pull cord into electrical signals that control a motorized window covering. In some embodiments, cord gestures that deflect the deflectable arm include pull sequences, numbers of pulls, strength of pulls, or combinations thereof. Additionally, in some embodiments, a controller receives the cord gestures and translates the cord gestures into operational commands to control and operate a window covering gearbox assembly.
