1. A control device configured for use in a load control system to control an electrical load external to the control device, the control device comprising:
an actuation member having a front surface that defines a touch sensitive surface along at least a portion of the front surface;
a plurality of capacitive touch pads located behind the actuation member and adjacent to the touch sensitive surface; and
a control circuit configured to determine a touch actuation along the touch sensitive surface in response to an output signal received from at least one of the plurality of capacitive touch pads;
wherein the control circuit is configured to provide a quicker response time to control an amount of power delivered to the electrical load in response to the touch actuation when operating in an active touch mode as compared to when operating in an inactive touch mode.
