ABSTRACT:
An electronic cabinet having a conductive frame and a conductive removable access panel or door is grounded by a ground button. The ground button comprises a donut-shaped core of resilient material supported by a mounting plate. A layer of knitted-metal wire mesh at least partially surrounds the exterior of the core and the mounting plate. The button is constructed to be mounted to one surface of the cabinet with the layer of knitted-metal wire mesh in contact therewith. When the access panel or door is closed, the button is deformed between the frame and access panel or door to provide a positive conductive leak path therebetween.
