The load control system includes a transmitter and a wall control/receiver, each having a control actuator for adjusting the power supplied to the load. Control can be obtained by either the transmitter or the wall control/receiver immediately upon manipulation of either control actuator, with the adjustment in power level occurring substantially instantaneously. Communication between the transmitter and the wall control/receiver is by digitally encoded infrared signal.Field of SearchIncluding single unidirectional element with bidirectional passUsing single unidirectional element with bidirectional pass With a three or more terminal semiconductive device in trigger circuit Including ramp generator or controlled capacitor charging With passive element only in trigger circuit LAMP DIMMER STRUCTURE REMOTE SENSING SWITCHING SYSTEMS Plural switches Lazy-man switch type Selectively actuated Condition responsive Electrical Radiant energy controlled regulation of the current supply for the load device CURRENT AND/OR VOLTAGE REGULATION Independent operators interlocked Multiple push-button only one operable at a time Sliding contact For relays or solenoids Radio link Wireless link Transmitter for remote control signal | |
