  • Patent number: 9148932
    Abstract: A dimmer switch uses different fade rates when turning on or off lighting load depending on a device used to adjust the lighting load. For example, the dimmer switch uses a first fade rate when turning off a lighting load in response to an actuation of a local actuator or accessory switch and uses a second fade rate faster than the first fade rate when turning off the lighting load in response to an actuation of a connected three-way switch may be provided. The dimmer switch may slowly turn off the lighting load in response to an actuation of the actuator to provide an aesthetically pleasing reduction in the intensity of the lighting load. When a user actuates the three-way switch to turn off the lighting load, the dimmer switch quickly reduces the intensity of the lighting load to approximately zero percent as may be expected by the user.
