Abstract
An electronically controlled sewing machine having buttonhole capability and a reverse stitch actuating switch wherein actuation of the reverse switch during a buttonholing operation will initiate the second step of the buttonhole. Signals characteristic of selection of a buttonhole mode of operation are used in a logic combination to enable reverse selecting means to be used to initiate the second step of the buttonhole while inhibiting its use to implement reverse stitching. Absence of these characteristic signals will permit the reverse selecting means to be used to implement reverse stitching.
