Abstract
Apparatus for electrostatically grounding a person working in an electronics factory or other area where static electricity in persons is a problem. There is an electrostatic drain to drain static electricity to ground from a predetermined region of the person's clothing, and an assembly to drain electricity from the person to the predetermined region for making of electrical connection to the drain means and for conduction of static electricity to it. The assembly comprises an electrically conductive tab, and a thin flexible synthetic resin substrate, and a conductive film on the substrate, and a discrete high-resistance resistor mounted on the film and having its terminal portions electrically connected to spaced and mutually electrically isolated regions of the film. An end of the tab is electrically connected to the conductive film, and a package formed of thin electrically-insulating water-resistant flexible sheet material is provided. The sheet material encloses the resistor and at least a large part of the substrate.
