Abstract:
1. A signal processing circuit for detecting vibration applied to an acceleration switch based on an open/closed state of the acceleration switch, the signal processing circuit comprising: a main determination section configured for connection to the acceleration switch for comparing an output of the acceleration switch to a preset first determination criterion to thereby determine the vibration applied to the acceleration switch; a power supply control section for controlling supply of power based on a result of the determination made by the main determination section; a main control section for controlling a control target based on the power supplied from the power supply control section; and a sensor for detecting a physical quantity applied to the sensor based on the power supplied from the power supply control section, and for outputting a result of the detection as physical quantity measurement information, wherein the power supply control section controls the supply of the power to at least one of the main control section and the sensor based on the result of the determination made by the main determination section as to the vibration applied to the acceleration switch.
