The ESE18 series is designed for miniaturized and lightweight applications, such as the media detection mechanism in portable equipment. Standing at a size of 4.4mm x 4.0mm x 1.2mm, it is ideal for applications where size is an issue. Reliability is achieved with a self-wiping leaf spring contact construction design. Power consumption is reduced with the normally closed circuit, while a normally open model is also available. It is a surface mounted type switch with embossed tape packaging and it supports reflow soldering. The switch travel length is available at 1.5 mm and 2.15 mm.
