Schematic symbol

What does an electrical match look like on an electrical schematic? Are there standardized symbols? Swooch (talk) 06:52, 30 April 2012 (UTC)Reply

two kinds of devices

edit

This article currently confuses two different kinds of devices:

  • One kind of device made of a pyrogen-coated heating wire, designed for one-time use, using only relatively low voltage, designed to light something that can only be lit once, such as fireworks or model rockets.
  • Another kind of device that generates a relatively high voltage to create sparks across its spark-gap, such as piezo ignition or electronic ignition, designed to light something that can be lit many times, such as propane grills, natural gas hot water heaters, the "combustion" part of internal combustion engines, etc.

My close neighbors use the terms "electric match", "electric igniter", and "igniter" interchangeably as synonyms to refer exclusively to the heating-wire devices, and never refer to the spark-gap devices. My reading of the pyrotechnic initiator article and the references in this article seem to agree with that usage.

How can we avoid confusion in this article? Should we (a) reduce this article to focus on electric matches, by removing all the spark-gap stuff -- perhaps moving that stuff to the "piezo ignition" article or the "electronic ignition" article? Or should we (b) keep an expanded, more general article that discusses both kinds of devices -- perhaps under some other name? --DavidCary (talk) 17:10, 26 July 2013 (UTC)Reply

An electric match is a device that uses an externally applied electric current to ignite a combustible compound. This image is a collage of three photographs depicting an electric match at the moment of ignition in the centre, together with the same match before detonation on the left and after detonation on the right. To ignite the match, a suitable electric voltage is applied to a heating element, typically a loop or coil of thin wire, which is encased in a quantity of a flammable pyrotechnic initiator fluid, which then ignites.
