。 In a sound switch that collects sound waves with a microphone and outputs an output signal when the sound wave signal level of the sound waves reaches a predetermined value or more, a sound wave signal of a predetermined value or more inputted to the microphone is converted into a sound wave signal pattern for a predetermined time width. A sound wave signal storage unit capable of storing a plurality of sound wave signal patterns as well as a plurality of sound wave signal patterns is compared with each of the continuously inputted sound wave signal patterns stored in the sound wave signal storage unit to determine whether the sound wave signal patterns are substantially the same pattern. A sound switch characterized in that it has a determination section that outputs an output signal when .
