Schurter Capacitive Hidden Switch (CHS) Metal Line Switches

Schurter Capacitive Hidden Switch (CHS) Metal Line Switches are intended for use behind non-conductive surfaces, enabling interface designers more flexibility in custom panel designs. These capacitive switches can be used as a single key or in arrays. The standard switches can be mounted behind a glass surface up to 2mm in thickness. The sensitivity level can be adjusted for mounting behind surface overlays such as plastic, porcelain, ceramic, granite, and more. The CHS series does not require mounting holes or switch openings that would allow for the ingress of liquids, dirt, or microbes. Schurter CHS Metal Line Switches are ideal for surfaces that require frequent cleaning, such as vending machines, ticketing kiosks, and other self-service kiosks. Additional applications include architectural design, professional / gourmet kitchens, and industrial. The CHS switches provide a rated lifetime of more than 100 million actuations.
