Description

Technical Field

[0001] The utility model belongs to the technical field of switches and relates to a new combination switch for a sewing machine. Background Art

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on a material, interweaving or sewing one or more layers of material. Sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products such as leather, plastic, and paper. The stitches produced by a sewing machine are neat, beautiful, smooth, and firm, and the sewing speed is fast and easy to use. This has led to art forms such as hand-push embroidery and computerized embroidery. Existing sewing machines rely on multiple switches, and these switches and multiple chips control the functions of the sewing machine. This results in the sewing machine not being able to function in an integrated manner, with complicated steps and troublesome debugging. Therefore, a new combination switch for a sewing machine is proposed to address the above issues. Utility Model Content
