Title: Indexing ring providing automatic continuity

Abstract: An indexing ring providing automatic continuity between metallic parts of an operator interface device and a support panel in which the operator interface device is mounted. Continuity between the operator interface device and support panel is automatically provided by a continuity rib integrally formed from the indexing feature of an indexing ring. The indexing ring is installed between the operator interface device and the support panel to ensure the relative position of the operator interface device with the support panel. As the indexing feature of the indexing ring is slidably received within the indexing features of the support panel and operator interface device a generally sharp distal edge of the continuity rib will cut through any corrosion protection, such as paint, which might be covering the support panel. Thus, a metal-to-metal connection providing electrical continuity is automatically established and maintained between the operator interface device, indexing ring and the support panel.
