Title:
HALF-CUT SWITCH FOR EARTHQUAKE SENSING ELECTRIC LIGHT
Document Type and Number:
Japanese Patent JP2017188486
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an earthquake sensing half-cut switch capable of surely detecting quakes caused by an earthquake, and turning on an existed indoor lighting.SOLUTION: An earthquake sensing half-cut switch comprises: a main switch with a role in a reset switch; a three-axial acceleration sensor that surely detects quakes; a timer circuit that automatically cancels a conductive state after the passage of a constant time; an operation start delay timer that is used for avoiding a reaction for the momentary quakes; and a power source part that supplies a DC power to the acceleration sensor or the like. The acceleration sensor that detects the quakes generates an electric signal and lightings lightening equipment by turning on the main switch, but the acceleration sensor is not reacted on the momentary quakes because the operation start delay timer is operated. The acceleration sensor can be manually reset by operating a switch operation part and operating the reset switch with the role in the main switch although the conductive state is automatically cancelled by a timer after the constant time has been passed from the lightening.SELECTED DRAWING: Figure 3
