Abstract:
A control device configured for use in a load control system to control one or more electrical loads may comprise an actuation member having a front surface defining a touch sensitive surface configured to detect a point actuation along at least a portion of the front surface, a touch sensitive circuit, and a control circuit. The touch sensitive device may comprise one or more receiving capacitive touch pads located behind the actuation member and arranged in a linear array adjacent to the touch sensitive surface. The control circuit may be configured to operate using different filtering techniques based on the state/mode of the control device and/or based on whether the positions of point actuations by a user along the touch sensitive surface indicate a fine tune or gross adjustment by the user. For example, the control circuit may generate an output signal using light/no filtering or using heavy filtering.
