Abstract
A zig-zag sewing machine has a series of cams juxtaposed on a drive shaft for controlling oscillation of a needle-bar cradle. Cam selection is achieved by a manual selector having two cam profiles, one of which controls a lever to space a feeler apart from the cams at the moment when the other cam profile controls another lever to move the feeler parallel to the drive shaft to change the cam with which the feeler cooperates.
