A spark is created by striking metal against a flint, or by pressing a button that compresses a piezoelectric crystal (piezo ignition), generating an electric arc. In naphtha lighters, the liquid is sufficiently volatile, and flammable vapour is present as soon as the top of the lighter is opened. Butane lighters combine the striking action with the opening of the valve to release gas. The spark ignites the flammable gas causing a flame to come out of the lighter which continues until either the top is closed (naphtha type), or the valve is released (butane type).[citation needed]
A metal enclosure with air holes generally surrounds the flame, and is designed to allow mixing of fuel and air while making the lighter less sensitive to wind. The high energy jet in butane lighters allows mixing to be accomplished by using Bernoulli's principle, so that the air hole(s) in this type tend to be much smaller and farther from the flame.[citation needed]
Specialized "windproof" butane lighters are manufactured for demanding conditions such as shipboard, high altitude, and wet climates. Some dedicated models double as synthetic rope cutters. Such lighters are often far hotter than normal lighters (those that use a "soft flame") and can burn in excess of 1,100 °C (2,010 °F). The windproof capabilities are not achieved from higher pressure fuel; windproof lighters use the same fuel (butane) as standard lighters, and therefore develop the same vapour pressure. Instead, windproof lighters mix the fuel with air and pass the butane–air mixture through a catalytic coil. An electric spark starts the initial flame, and soon the coil is hot enough to cause the fuel–air mixture to burn on contact
