ABSTRACT:
A modular analog/digital display for use in a cylindrical aircraft instrument housing is designed to enable the digital components to be assembled without interference to the analog meter mechanism. The digital display is of the leadless type and is clamped under compression to a circular circuit board with a pair of contact strips in registration with contacts formed on the circuit board and digital display. The design also features a screw-on dial pointer which facilitates the assembly of the digital display components and dial to the analog meter mechanism without interference.
