Abstract
A captured offset linear guide system for a lighting control device includes a faceplate having an elongated slot, a knob, an offset member, and a linear potentiometer. The offset member allows the linear potentiometer to be offset from the elongated slot of the faceplate to prevent dirt and dust from collecting on the potentiometer. Also, the offset linear guide system prevents insertion of an object into the internal structure of the lighting control device where it might come into contact with energized electrical components. The faceplate includes two guide rails, which hold the offset member close to the faceplate and allow for easy assembly of the faceplate to the lighting control device. Further, the faceplate includes an alignment rail, which prevents the offset member from rotating and further constrains the offset member to move in a straight line within the slot.
