PURPOSE:To provide a cord switch auto-driving device, which can be mounted on an electric lamp easily and operated automatically, by installing the cord switch driving part having a motor, power transmitting part, and takeup part in a position near the body of electric lamp, and connecting a control part separately from the driving part. CONSTITUTION:A cord switch driving part 1 is equipped with a motor 11, power transmitting part 12, takeup part 13 for cord 6, and power supply 14, and is provided with a control part 2 connected by an electric cord 5 to transmit signal so as to locate remotely. When a signal to connect the motor 11 with power supply 14 is sent from this control part 2 to the driving part 1 to operate the motor 11 for a certain time, the cord takeup part 13 is driven through the power transmitting part 12 to perform taking-up of the cord, and subsequent pulling-down actuates a switch 3. When lighting or putting-off of the light 4 is finished, the control part 2 gives a signal to operate subsequently the motor 11 is reverse direction for returning the cord 6 to its original position, and thus lighting or putting-off of the electric lamp is finished. This facilitates installation and provides automatic operation of lighting or putting-off. |
