WARNING - This is a high voltage device. Caution is required when using to avoid receiving an electric shock!
This is a battery powered high voltage pulse igniter (spark generator) with minimum output of 22,000 volts. Pushing the button generates a strong hot spark making it ideal for a potato gun ignition system.
Two output wires are supplied, one connects to a spade connector underneath and the other can be soldered to the brass tab on the outside of the battery holder or held in place by the button collar nut. If you are using this for a potato gun igntion you'll need to make your own electrodes (from brass rod or similar) with a 10mm gap for the spark to jump across.
ADVANTAGES OVER PUSHBUTTON PIEZO

Quieter compared to 'clack clack' piezo igniters
Continuous spark output while button is pressed

ABOUT POTATO GUNS
Despite what a lot of people think potato guns are NOT illegal in New Zealand but you do need a firearms license to own and use one (a bit of common sense helps too). This applies to combustion type potato guns, i.e. the sort that use deoderant, hairspray or similar gas fuel. Because they make an explosion (like the gunpowder in an ammunition round) to propel the projectile they are technically classed as a firearm.
NOTE
The photo shows two igniters so you can see it from different angles but the price is for one unit only.
