A modular electrical control system for installation in an electrical box of a premises includes a switch module configured to control power delivery to at least one external load, the switch module including a multi-position switch device that changes an operational mode of the switch module to off, toggle mode, or dimmer mode, and a removable user interface module configured to connect to the switch module, receive power from the switch module and display an interface in accordance with a setting of the multi-position switch device.

Three-position operating mode switch

A modular electrical control system includes a switch module, having at least an 'on' state and an 'off' state, configured to draw power from an AC power source and to control power delivery to at least one external load, the switch module including a detector that determines whether a neutral wire is connected to the switch module, and a removable user interface module configured to connect to the switch module and receive power from the switch module, wherein the switch module delivers a first amount of power to the user interface module when the detector determines that the neutral wire is connected to the switch module, and delivers a second amount of power to the user interface module lower than the first amount of power when the detector determines that the neutral wire is not connected to the switch module.

Modular electrical control system

A modular lighting control system is disclosed for lighting control, modular home electronic devices and home networking of modular electronic devices. The system includes a switch module having one or more magnets, a wireless power transmission coil, an infrared light transmitter and an infrared light receiver and a user interface module having one or more wireless power reception coils, one or more magnets, an infrared light emitter and an infrared light detector. The user interface module can be removably attached to and powered by one or more of the switch modules and communicate with one or more of the switch modules without any mechanical attachment or electrical connection on either the switch module or the user interface module.

Modular lighting control system

A method of controlling an electrical control system, the system including a switch module to control power delivery from a power source to at least one load, the switch module including first and second traveler lines to connect the switch module to a load or to a corresponding switch in a three-way configuration, the method including receiving, at the switch module, a first signal from the first traveler line, receiving, at the switch module, a second signal from the second traveler line, receiving, at the switch module, a third signal from a common line, where the common line is connected to the load or the power source, identifying a waveform pattern based on the first signal, second signal and third signal, determining a state of the load based on the identified waveform pattern, and controlling a display of a user interface based on the determined state of the load.

System and method for three-way switching

A user interface () comprises a layered structure defining one or more keys (). The layers can include a top layer (), a base layer (), and an interior layer () disposed therebetween. One or more layers are pliant and can be compressed. Magnetically permeable materials () form a closed loop (). A corresponding coil () is operable with the loop. Electrical properties of the closed loop change in response to user input. A control unit () is then configured to detect a change in the electrical properties when the pliant material is compressed. Where the change is greater than a predefined threshold, the control unit () discharges an energy storage device into the coil to provide a haptic response ().
