Electric match
From Wikipedia, the free encyclopedia
In pyrotechnics, an electric match is a device to ignite the end of a fuse under control of an externally applied electrical current. They are widely used in professional fireworks displays to control firing from a panel of manually operated switches, or from a computer interface. Electric matches typically consist of a pair of 22-gauge wires joined at the end with a smaller-diameter "bridge wire" that has been coated with a pyrotechnic initiator mixture formulated to ignite at relatively low temperatures.
