Abstract
A lighting control device for controlling the state and intensity level of at least one lamp. The device includes a user-actuatable intensity selector for selecting a desired intensity level between a minimum intensity level and a maximum intensity level, a control switch for generating control signals representative of preselected states and intensity levels of the lamp in response to an input, and a control responsive to the intensity selector and the control switch for causing the lamp to fade from an off state to the desired intensity level when the input from a user from a user causes a single switch closure of transitory duration, such fade occurring at a first fade rate, fade from any intensity level to the maximum intensity level when the input from a user comprises two switch closures of transitory duration in rapid succession, such fade occurring at a second fade rate, and fade from the desired intensity level to an off state when the input from a user comprises a single switch closure of more than a transitory duration, such fade occurring at a third fade rate, each of such fade rates being non-instantaneous.
