how to wire a toggle switch with 4 prongs

A push button switch with four prongs is usually a (DPDT) switch, also known as a double pole double switch. It consists of a toggle lever and four electrical connection pins for connecting or disconnecting a circuit.

In its simplest form, a toggle switch is a mechanical switch, operated by a lever or toggle, that moves up and down to effect the opening or closing of a connection between two terminals.

When the switch is in the “on” position, the circuit is broken and current can flow through the switch. When the switch is in the “off” position, the circuit is open and current cannot flow through the switch.

The four-pin toggle switch is usually widely evaluated in electronic equipment and mechanical equipment, and can control circuit switching, direction control, circuit selection mode switching and other functions.

For example, in the application of controlling the forward rotation of the motor and accessories, the four-pin toggle switch can control the forward rotation and accessories of the motor; in audio equipment, it can be used to switch the input and output of audio signals.

The four-pin toggle switch is also called a switch (Double Pole Double Throw Switch) because it has two electrical polarities, and each polarity has two connecting pins, which can control the switching of two circuits. When the toggle lever is operated, it changes the electrical connections inside, connecting or breaking the circuit. Each of the two electrical polarities has two connecting pins, so it is possible to control the switching of two circuits.

With the continuous development of technology, the types and functions of toggle switches are constantly increasing to meet the changing market needs.

Application

1. Lighting equipment: used to control the switch or dimming of lamps.
2. Household appliances: such as control switches in household appliances such as rice cookers, induction cookers, and water heaters.
3. Electronic equipment: such as control switches in electronic equipment such as televisions and audio equipment.
4. Mechanical equipment: such as control switches in mechanical equipment such as industrial robots and automated assembly lines.
5. Cars and aircraft: such as control switches for lights and fans in cars, control panels in aircraft, etc.
6. Power supply equipment: such as power switch, battery switch, etc.

Working principle

The working principle of the toggle switch is based on the principle of mechanical contacts.

When the button is pressed, the spring inside the button moves the button from the released position to the pressed position, causing the movable contacts on the button to make contact with the fixed contacts, thus forming an electrical circuit.

When the button is released, the spring moves the button from the depressed position back to the released position, causing the movable contacts on the button to separate from the fixed contacts, breaking the circuit.

The mechanical contacts of the toggle switch are usually made of metal materials, such as copper, silver, etc.These materials have good electrical conductivity and mechanical strength, and can withstand thousands of pressing operations.

When the button is pressed, the movable contact will make contact with the fixed contact, forming a low impedance circuit; when the button is released, the movable contact will separate from the fixed contact, cutting off the circuit.

It should be noted that since the mechanical contacts of the button switch are made of metal materials, problems such as contact oxidation and wear may occur after long-term use, resulting in reduced electrical performance or even failure.

Therefore, when using the toggle switch, it is necessary to pay attention to selecting the appropriate quality and service life, and to perform proper maintenance.

Structure

1. Enclosure: The toggle switch usually consists of a plastic enclosure to protect the electrical circuits and mechanical parts inside the switch. The material and design of the housing can affect the switch’s water, dust and mechanical strength properties.
2. Switch lever: The switch lever is used to control the on-off state of the switch. There are usually different shapes, such as round, rectangular and oval, etc., and the switch state can be switched by flipping the switch lever. The shape and length of the rod can be customized according to the purpose of the switch and the installation environment.
3. Pin: The pin is connected to the circuit inside the switch. A bipolar switch has 4pins, each pin is responsible for turning on and off a circuit. The material and contact area of ​​the pins can affect the electrical performance and life of the switch.
4. Spring: The spring is responsible for connecting the pin with the contact inside the switch, thereby controlling the circuit on and off. When the switch lever is toggled, the spring separates the pins from the contacts, opening the circuit. The material and spring rate of the spring can affect the mechanical performance and life of the switch.
5. Accessories: The 4-pin toggle switch may also include other accessories, such as protective covers, sealing rings, and fixing screws, to improve the waterproof, dustproof, and mechanical strength of the switch. The design and material selection of accessories can be optimized according to different application scenarios to enhance the reliability and durability of the switch.

Prospects

Specific wiring method

The wiring method of the four-pin button switch is very simple

First, prepare a battery, a four-pin button switch, and two LED lights.

Connect the positive pole of the battery to one terminal of the button switch, connect the other terminal to the LED light, and then connect the LED light to the negative pole of the battery. form a series closed circuit.

At this time, toggle the button switch, when the button switch points to ON, the LED light is on at the same time, and when it is pointing to OFF, the LED light is off at the same time.

These small toggle switches have the advantage of being compact and simple to install and use. They are usually constructed using plastic or metal materials and can be utilized in various applications, including regulating circuit switching states in household appliances or industrial equipment.
