Why are TouchSensor TouchCells more reliable/durable than mechanical or membrane switches?
TouchCells are solid-state devices with no moving parts. With no moving parts to wear out, the wear and tear issues which plague conventional switches are inherently eliminated. Additionally, because TouchCells are mounted behind solid substrates, user and environmental abuse become a non-factor. Furthermore, TouchCells are recognized as fail-safe device by Underwriters Laboratories (UL File # E187820).
