Title:
熱線センサ付自動スイッチ
Document Type and Number:
Japanese Patent JP3620347
Kind Code:
B2
Abstract:
The automatic gang switch having a heat ray sensor is fixedly mounted on a mounting frame having a generally rectangular opening. The length of a housing of the switch is approximately two thirds of that of the generally rectangular opening of the mounting frame, while the width of the housing is approximately equal to that of the generally rectangular opening of the mounting frame. The switch includes a human body detecting section for detecting heat rays emitted from a human body and a circuit section. The circuit section includes a control circuit for generating a control signal to turn a load on for a predetermined operation holding time when the human body detecting section generates a detection signal, a load control circuit connected to a power source and the load in series for turning on or off power supply to the load depending on the control signal, an off-time power circuit connected in parallel with the load control circuit and having an input impedance with which the load is not driven when the load control circuit is off, the off-time power circuit supplying an electric power to the control circuit when the load control circuit is off, and an on-time power circuit for supplying the electric power to the control circuit when the load control circuit is on. The switch further includes a time setting section for setting an operation holding time and a mode setting section for changing over an operation mode of the control circuit.
