Title:
PROGRAMMABLE WALL SWITCH
Document Type and Number:
Japanese Patent JPS5986195
Kind Code:
A
Abstract:
A programmable wall switch for controlling the time for turning on and for turning off an incandescent light includes a rectifying circuit for producing from the AC power line a selected DC voltage. The switch includes a microprocessor powered by this DC voltage for turning on a light at any one of several selected times and for turning off the light at one of an additional corresponding several selected times. A time display is provided for displaying the time as well as for allowing a user to review the programmed status of the switch at any one of several selected times. A signal is generated at each zero crossing of the AC power line which is supplied to the microprocessor. The microprocessor produces output signals which turn on, turn off or dim the light at selected times. The ability of the microprocessor to dim the light further enhances the appearance of human occupancy when the switch is used to simulate occupancy of a vacant building.
