  • Patent number: 11937355
    Abstract: A dimmer switch system for dimming a load includes a master dimmer structured to be electrically connected to a power source and the load and to control dimming of the load by regulating power provided from the power source to the load, and at least one accessory dimmer structured to be electrically connected to the master dimmer via a traveler conductor. The master dimmer is structured to generate a first control signal on the traveler conductor to indicate a type of the master dimmer, and the at least one accessory dimmer is structured to selectively enable or disable one or more functions of the at least one accessory dimmer based on the type of the master dimmer.
    Type: Grant

  • Patent number: 10869371
    Abstract: A dimmer switch system for dimming a load includes a master dimmer structured to be electrically connected to a power source and the load and to control dimming of the load by regulating power provided from the power source to the load, and at least one accessory dimmer structured to be electrically connected to the master dimmer via a traveler conductor. The master dimmer includes a first visual load status indicator structured to emit light in a plurality of colors. The at least one accessory dimmer includes a second visual load status indicator structured to emit light in a plurality of colors, and is structured to set a color of light emitted by the second visual load status indicator based on a first control signal generated by the master dimmer on the traveler conductor, and to generate a second control signal on the traveler conductor.

  • Patent number: 10798796
    Abstract: A dimmer switch system for dimming a load includes a master dimmer structured to be electrically connected to a power source and the load and to control dimming of the load by regulating power provided from the power source to the load, and at least one accessory dimmer structured to be electrically connected to the master dimmer via a traveler conductor. The master dimmer is structured to generate a first control signal on the traveler conductor during one of a positive or negative half-cycle of power from the power source. The at least one accessory dimmer is structured to generate a second control signal on the traveler conductor during the other of the positive or negative half-cycle of power from the power source.
