Pull wire lighters are low explosive devises used to initiate safety fuse. It consists of a paper tube, White plastic pull cap and safety clip. Inside the tube is a pull wire coated with red phosphorus, which is pulled through an ignition cup containing potassium chlorate and charcoal. A fuse gripping ferule is located at the mouth of the tube and a fuse stop ferule is located at the back end of the tube to stop the fuse from pushing up into the ignition cup and pull wire. When the white cap is pulled, the wire is pulled through the ignition cup and emits a directional spark towards the fuse, thus lighting the black powder fuse train of a Safety fuse cap assembly
