a small metal or plastic part that holds the bobbin (a small spool of thread) and ensures the bobbin thread is in the correct position to interlock with the upper thread, creating a stitch

a plate that sits below the needle and presser foot, with a small opening allowing the bobbin thread to come out and the needle to pass through to make stitches

toothed metal bars located under the presser foot that move the fabric through the machine, ensuring smooth and even stitching

foot control (or foot pedal) is used to start and stop the machine and control its speed, while a knee control (or knee lift) is a lever that allows you to raise and lower the presser foot with your knee, freeing your hands for fabric handling

a large, round knob used to manually raise and lower the needle

a single switch that controls both the machine's motor and the built-in light, turning them on or off simultaneously

a lever, typically located at the back of the machine, that raises and lowers the presser foot, allowing you to insert and remove fabric and change presser feet

a crucial part that moves up and down, synchronized with the needle bar, to pull the upper thread from the spool, feed it through the machine, and lift it back up after each stitch, ensuring proper thread tension and stitch formation
