Slider (lock or pawl) - a movable part of a zipper that provides opening and closing of the links (teeth) of the fastener. The slider consists of two elements: 1. Lock - provides connection or disconnection of lightning; 2. Slider (puller) is the "handle" of the slider. Different types of zippers require different types of sliders: - Haberdashery: It is used when sewing bags and other haberdashery products, where fixation of the slider in the direction of travel with a zipper is not important, but smooth running and appearance is important, since haberdashery sliders look smaller and more accurate than automatic sliders. - Automatic machines: They have a mechanism inside for fixing on any part of the zipper. As a rule, they are a little more massive than haberdashery; such runners are suitable for sewing shoes, outerwear and various equipment. - Semiautomatic devices: Unlike automatic runners, they do not contain an internal mechanism that blocks the movement. To fix it, you need to fix the slider with a stopper on the slider. They are often used when sewing jeans. Runners come in different sizes to suit specific types of zippers. The color or finish of the slider is matched to the color of the zipper link.
