An automatic control means for overriding the manually operable fast/slow control switch of a sewing machine to assure slow speed operation while the machine is operating in skip stitch mode, such as while basting to facilitate positive latching and unlatching of the needle bar. The automatic control means cooperates with the needle bar lateral jogging mechanism of the sewing machine such that when the needle bar is jogged beyond a predetermined range of laterally jogged positions, wherein skip stitch mode is effected, the automatic control means will automatically impose slow speed operation independent of the setting of the fast/slow control switch as selected by the operator.
