Abstract: A control mechanism for use with a fluorescent lighting unit having at least first and second lamps utilizing a line switch. The mechanism includes an AC toggle which alternately interrupts and connects electrical power from a source to one of the first and second lamps, only. The toggle is responsive to the successive opening and closing of the line switch. A reset feature overrides the means for alternately interrupting and connecting power source to one of the pair of lamps by connecting power from the source to the second lamp. The reset feature is also responsive to the operation of the line switch.

Abstract: A wall box mounted remotely operated voltage module utilizing a low voltage DC control signal which is remotely generated. A power semi conductor device is triggered to deliver a predetermined amount of power from the source of AC electrical power to a load. The AC electrical power is rectified and transformed to produce a low voltage rectified DC signal. A comparator generates a triggering signal to the power semi conductor utilizing the low voltage rectified DC signal and remotely generated low voltage DC control signal as imputs. The comparator also serves as a compensator for changes in the voltage of the AC electrical power from the source.

Abstract: A panel controlling multiple lighting intensities of a multiplicity of lights in conjunction with a remote lighting dimmer module which utilizes operators mechanically movable to operate potentiometers. Each potentiometer is capable of setting an intensity level of a particular light of the multiplicity of lights. A display is also employed which indicates a lighting level of each of the multiplicity of lights associated with each operator and corresponding potentiometer. The operators and display are supported by a chassis which is mountable in an electrical wall box. Information may be stored which defines a lighting scene in terms of an intensity level of each light of the multiplicity of lights which is set by the operators in the chassis. The intensity level information may be retrieved and transported to a dimmer module which sets the intensity level in each light. One scene may be set into the multiplicity of lights while another scene may be previewed on the display on the chassis.

Abstract: A circuit for controlling the initiation and operation of a phase control circuit employed in voltage regulation to a load such as dimming lights. The circuit uses a power semi-conductor which is triggered by a "walk-in" circuit. The "walk-in" circuit includes a regulator diode across a diode bridge which stabilizes the output of the load, such as a level of lighting.
