| The "Loudness Kill Switch" reacts to the loudness of music emmited from a speaker. The mechanical construction consists of an aluminium ball applied to a loudspeaker, moving towards a copper rod when music is played. The circuit will be closed if the aluminium ball gets in contact with the copper rod. | |||
| That happening a LED will light up and the loudspeaker (connected to an amplifier again connected to a solid state relay)  will turn off for ca. 30 seconds. This time passed the loudspeaker will turn on as the LED will turn off again.  | |||
| : | To improve:   | ||
| The circuit will only be closed if there is enough base in the music.   | |||
