Three Sewing Machine Foot Pedal Wiring Diagram

Sewing machines are an essential tool that every tailor, seamstress, or hobbyist must possess. As basic as sewing machines may seem, they have countless parts that must function correctly to achieve quality results. One of these parts is the foot pedal, which controls the machine’s speed. In this article, we will discuss the three sewing machine foot pedal wiring diagrams in detail.

Types of Sewing Machine Foot Pedals

There are three types of sewing machine foot pedals available in the market today. These are the mechanical, electronic, and computer-controlled foot pedals.

The mechanical foot pedals are used in older sewing machines that have a mechanical motor. The pedal has a metal bar that moves back and forth, and when pressed, it operates the motor. The electronic foot pedal is commonly used in modern sewing machines, where the motor is controlled by an electrical circuit. A computer-controlled foot pedal is used in advanced sewing machines that have a computer-controlled motor.

Mechanical Foot Pedal Wiring Diagram

The mechanical foot pedal wiring diagram is simple since it only contains a few wires. The wires in the mechanical foot pedal are connected to the metal bar that controls the motor’s movement. The wiring diagram consists of two wires that are connected to the motor, and two wires are connected to the pedal.

The two wires that go to the motor are red and black. The red wire is connected to the positive terminal, and the black wire is connected to the negative terminal. The two wires that go to the pedal are green and white. The green wire is connected to the pedal’s top, and the white wire is connected to the bottom of the pedal.

The wiring diagram for the mechanical foot pedal is easy to understand and can be easily repaired if damaged.

Electronic Foot Pedal Wiring Diagram

The electronic foot pedal wiring diagram is more complex than the mechanical foot pedal diagram. The electronic foot pedal contains a potentiometer that controls the motor’s speed, and the potentiometer requires an electrical circuit for it to work.

The electronic foot pedal wiring diagram consists of three wires that connect to the motor and four wires that connect to the potentiometer. The three wires that connect to the motor are red, black, and white. The red wire is connected to the positive terminal, the black wire is connected to the negative terminal, and the white wire is connected to the motor’s middle terminal.

The four wires that connect to the potentiometer are green, white, red, and black. The green wire is connected to the potentiometer’s top, the white wire is connected to the middle terminal, the red wire is connected to the bottom of the potentiometer, and the black wire is connected to the circuit board.

The wiring diagram for the electronic foot pedal is more complicated than the mechanical foot pedal diagram, but it is still easy to understand and can be repaired if damaged.

Computer-Controlled Foot Pedal Wiring Diagram

The computer-controlled foot pedal is the most advanced foot pedal used in modern sewing machines. The foot pedal is connected to a computer that controls the motor’s movement. The computer-controlled foot pedal wiring diagram is complex and requires professional expertise to repair.

The wiring diagram for the computer-controlled foot pedal consists of multiple wires that are connected to the motor, computer, and pedal. The wiring diagram includes wires of different colors, such as blue, green, yellow, purple, and red.

The computer-controlled foot pedal wiring diagram requires expertise to understand and repair, and it is not recommended for beginners to attempt any repairs. It is best to seek professional help if the foot pedal is damaged.
