BERÜHRUNGSLOSES BETÄTIGUNGSSYSTEM MIT GEERDETER OBERFLÄCHE

摘要

A dead front actuating assembly actuates a device in standard ambient light conditions. The dead front actuating assembly includes a housing defining a periphery and an interior volume. A cover plate is fixedly secured to the housing at the periphery. The cover plate defines an inboard surface facing the interior volume and an outboard surface opposite the inboard surface. The outboard surface is opaque in standard ambient light conditions. The dead front actuating assembly also includes a switch that is operatively connected to the inboard surface of the cover plate at a defined location for toggling the device between on and off conditions. The dead front actuating assembly also includes a presence sensor identifying when an operator is disposed adjacent the cover plate. A back light inside the housing illuminates the cover plate such that light passes through the cover plate and out the outboard surface to illuminate the switch for the operator.
