Abstract

This switch utilizes an opaque membrane which, in operation, is the only moving part. The switch is designed so that individual calibration is unnecessary. When flow of air to be detected distorts the membrane, the resulting movement of the membrane out of the path of associated photo-optics provides the useful output switching action.
