How does a butane lighter work?
Operation On the inside of a lighter there is a wick. This gets soaked in butane and is ultimately what sustains the flame when you use your fingers to light it. When you press down the button on the lighter to ignite the flame a small piece of metal is struck against a flint, which creates a spark. At the same time, a small valve is opened which releases gas into the lighter. The spark ignites the wick which ignites the gas which produces the flame. Letting go of the button stops the process completely by cutting off the gas. Refilling The process of refilling a butane lighter is simple. On the bottom of the unit is a hole referred to as the “refill hole.” Once you’ve purchased a can of butane from any gas station or tobacco shop, press the nozzle of the can into the hole. Squeeze the can to release butane into the lighter. The lighter will make a hissing noise as butane is replacing air. When the hissing noise stops, the lighter is full.
