The difference between an electric sewing machine and a manual sewing machine is only the method of propulsion. The electric machine uses an electric motor, while the manual machine uses a hand crank or foot pump to power it. The actual sewing machine is the same.
An electric sewing machine does it's work by using electricity to move the needle up and down, and rotate the bobbin. The mechanical parts of a manual sewing machine, had to be set in motion by turning a handle, or pedal. An electric sewing machine has an electric motor attached to these rotating parts, by belt or gearing and operated by a foot switch. This makes it less tiring on the arms or feet, you can keep sewing faster and longer.
The light on a sewing machine helps you see what you're sewing with ease. When sewing, precision and details are essential, so being able to clearly see the needle, thread, stitches, and details are necessary.
theory of sewing machine
It doesn't have one. A lot of sewing machines don't have on/off switches apart for working the light. The foot pedal usually disconnects the power when not pressed but this can not be relied on. Therefore you should never leave a sewing machine plugged in when not in use. Often the early models have a suppression capacitor in the foot pedal that can go short circuit making the machine run on its own.
It actually has no on/off switch and no light on it. You only need to plug it in and push the foot pedal to start sewing.
