Turning on and off a piezo-electric lighter (the one with no wheel, just a button).
The sound consists of two separate sounds – turning on and turning off, so that you could easily locate the on and off moments. It can be mixed with a mild burning gas sound, when the sound is really close up in the picture or important.
The two sounds in the zip-file:
Piezo-electric Lighter on – 0:01
Piezo-electric Lighter off – 0:01
