Schurter Capacitive Hidden Change (CHS) Metallic Line Switches


Schurter Capacitive Hidden Change (CHS) Metallic Line Switches are supposed to be used behind non-conductive surfaces, enabling interface designers extra flexibility in customized panel designs. These capacitive switches can be utilized as a single key or in arrays. The usual switches could be mounted behind a glass floor as much as 2mm in thickness. The sensitivity stage could be adjusted for mounting behind floor overlays similar to plastic, porcelain, ceramic, granite, and extra. The CHS sequence doesn’t require mounting holes or change openings that might permit for the ingress of liquids, dust, or microbes. Schurter CHS Metallic Line Switches are perfect for surfaces that require frequent cleansing, similar to merchandising machines, ticketing kiosks, and different self-service kiosks. Further functions embrace architectural design, skilled / gourmand kitchens, and industrial. The CHS switches present a rated lifetime of greater than 100 million actuations.
