Abstract
The invention comprises apparatus for performing a switching function in aircraft display instruments for providing a high contrast annunciation or indication thereof having a pair of transversal members disposed such that the depression of one of the members causes the rocker arm of a rocker switch engaged therewith to actuate according to the respective member. A linking member pivotally coupled between the two transversal members rotates through a fixed angle in response to the opposing movements of the transversal members causing a pivotally fastened indicator member with which it communicates to rotate such that a portion of the indicator member is rotated toward the face of the display instrument and provides an appropriate annunciation of the switch status.
