Abstract
A modular panel of dual filament tungsten lamp switches with current limiting, fault indicating, continuous lamp filament testing, and remote control switching capabilities. In one embodiment, the dual filament, self monitoring tungsten lamps are mounted as switches in an array and identified by row and column, the panel including a drum assembly rotatable to a related one of the rows and carrying indicia indicative of the circuits associated with the lamp in each column in the selected row. In a second embodiment, the dual filament, self-monitoring lamps are mounted as switches in an array. Each lamp or the lens cover associated therewith includes circuit identifying indicia visible in daylight by normal contrast and illuminated sufficiently by the lamps for visibility in a dark adapted environment such as the cockpit of an aircraft at night.
