Abstract
The indicator includes a ball bearing supported shaft which is coupled to the sewing machine main shaft, and carries plastic discs with permanent magnets. The discs can be angularly shifted, and their independent control is ensured by spacers with lugs in the groove of the shaft. The magnets control reed switches connected to the sewing machine controls.
