Reap the benefits of capacitance

Schurter’s invisible, hygienic capacitive hidden switch (CHS) is now available via Rutronik. The switch can be hidden as it functions without mounting holes. Invisible installation suits hygiene applications such as medical and food products.

The CHS attaches behind the surface using transfer adhesive tape. This eliminates drill holes and plug-in slots which aids cleaning. Likewise, there are no moving parts. Thus, bacteria, viruses or fungi can’t settle on the user surface.

The switch tolerates wiping movements and liquids, only triggering when the button is touched. For optimal functionality, the distance between sensor and finger may be up to 2mm.

Three versions are offered: without illumination; with optical feedback; and potted with lighting for demanding use in rough environments.

Benefits include: water tolerant, surface installation, wear-free, wipe resistant/easy cleaning, 3M 468MP transfer adhesive tape and low installation depth.
