摘要： An electric lamp holder comprises an electric lamp support and a housing therefor. The housing is of cylindrical form, one end and an adjacent cylindrical wall portion of the housing being of glass, and the remainder of the housing being of a metal having a coefficient of expansion which is substantially the same as that of the glass. Electrical connection to the electric lamp carried by the support is provided by a pair of resilient electrical contacts extending through the glass end wall of the housing. A plurality of these holders are mounted within a casing of a pressurized indicating instrument to illuminate from the rear a display face of the instrument. The housings are air-tight and are mounted in apertures in the casing, air-tight seals being provided between the housings and the instrument casing so as to enable the electric lamps to be replaced without depressurizing the instrument.
