How To Wire A 3 Way Toggle Switch
A 3 way toggle switch is an electrical device commonly used to manage the state of a circuit by either turning it on or off. Its name comes from its unique method of operation, which involves lightly pressing or clicking a lever forward or backward. Typically, toggle switches consists of a lever, a mounting bracket for securing the switch, and one or more sets of electrical contacts.
Toggle switches come in four main types:
Miniature switches, which have mounting holes typically measuring 6mm or 8mm and are commonly used in sound equipment and desk lamps.
High-current switches, which can handle 15A or more and require a 12mm mounting hole.
toggle light switch, which have a good indication effect and provide visual feedback when the switch is on or off.
Waterproof lighted toggle switches, which feature a waterproof ring inside the switch and a waterproof material coating on the outside to protect against moisture.
When choosing a toggle switch, it’s important to consider the instantaneous current at different current levels:
Yulin is a domestic design company that offers a self-designed waterproof toggle switch with a light. This product comes in a range of monochrome and two-color options, and features a tail made of glue to enhance its waterproof performance. The switch typically requires a 16mm mounting hole and is well-suited for use in yachts, modified cars, motorcycles, automation equipment, and other tools.
Definition
In the case of direct current, the instantaneous current can be more than three times higher than the normal circuit, so it’s typically multiplied by 3.5 to calculate the instantaneous current and prevent damage to the switch. The amount of current the machine requires to operate the switch can be calculated using the formula P=UI, where power equals voltage times current.
Toggle switches can be classified according to their functions, which include ON-OFF switches, ON-ON switches, ON-OFF-ON switches, MOMENTARY TOGGLE SIWTCH (on) off toggle switch , (ON) OFF ON (ON) OFF(ON)
A 12v toggle switch is an “ON-OFF” switch that opens one side and closes the other. A 3 position toggle switch is divided into two types: “ON-ON” and “ON-OFF-ON”. While the wiring for both types is the same, only one side of the line can be chosen to work at a time and cannot work simultaneously. An OFF switch can be used to ensure that neither side of the line works.
reliable connection.
Toggle switches are typically available with a choice of pins or screw feet. They come in a variety of styles, with two to four pin, as well as 3-pin, 6-pin, 9-pin, and 12-pin options, which can be selected based on the specific requirements of the application.

Pins and screw feet are types of electrical components used to fix and connect circuits. Pins are electrical components that are fixed and connected by being inserted into holes in the circuit board. They are typically available in single-row, double-row, and three-row configurations. The pin is inserted into the hole on the circuit board, and is fixed and connected by friction and pressure. This method of connection offers the advantages of simple installation and reliable performance.
Pins have the advantage of being easy to install and providing a reliable connection, making them suitable for applications that require convenient installation, small size, and frequent connection. However, pins have a small connection area, which can lead to loosening and is not suitable for applications that require a high level of connection firmness. Additionally, because pins need to be inserted into holes, they cannot be directly fixed onto the board, requiring other means of fixing.
Screw feet are electrical components that are connected to the circuit board using screws, which come in various types, such as round heads, flat heads, and semicircles. Screw feet are fixed onto the circuit board using screws, which can be easily replaced, disassembled, and maintained as needed. This method of connection offers the advantages of easy installation and high reliability.
The advantage of screw feet is their firm and reliable connection, replaceability, and suitability for applications that require reliable connection and easy replacement. However, the disadvantage of screw feet is that installation and disassembly require tools, such as screwdrivers, which can be relatively troublesome, and their applicability is not as wide as that of pins.
Types:
An SPST switch, or Single Pole Single Throw switch, has only one blade and one contact, and can control only one circuit switch. It has three terminals that can be used to switch between two different circuits.
A DPDT switch, or Double Pole Double Throw switch, has two blades and two contacts, and can control the switch of two circuits, switching between them. It has six terminals that can be switched between two circuits at two different locations.
used to connect switches and circuits. paraphrase
The 3 way toggle switch is an electronic switch that typically consists of several components, including:
Housing: This is usually made of metal or plastic and serves to protect the internal components while also improving the mechanical strength and durability of the switch.
Rocker: The rocker is often made of metal and is used to manually connect and disconnect the circuit.
Contacts: These are usually made of copper or silver and are used to establish or break the connection between the circuits.
Springs: These are typically made of metal and are used to control the connection and disconnection of the contacts.
Fasteners: These are usually made of metal or plastic and are used to hold the rocker and contact of the switch in place.
Terminals: These are usually made of metal and are used to connect the switch to the circuit.
Waterproof Cap:A small plastic or rubber cap used to protect electronic components from water, dust, corrosion, etc. It is usually placed on component terminals to protect them from the outside environment.
Protective Cover:It is usually a lid-like part that is installed on the button switch to cover the operating part of the switch and play a protective role to avoid collision or damage to the operating part by external objects.
The design of the air defense cover usually takes into account the size, shape and mode of operation of the switch, ensuring that the air defense cover can closely cover the operating part of the switch, and can be perfectly matched with the switch itself.
To wire a toggle switch with 3 prongs, the positive terminal of the power supply is connected to the common contact C. One light cable is connected to the NC (Normally Closed) contact, and another light cable is connected to the NO (Normally Open) contact. Two light cables are connected to the negative power terminal.
In the ON-OFF-ON type of toggle switch, when the switch is turned to the middle, the right light is turned to the left, and the left light is turned to the right.
In the ON-on type of 3pin toggle switch, there will not be two lights that are not working, and there will always be one indicator working ON both routes.
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. Furthermore, these switches typically exhibit good reliability and durability, enabling them to endure numerous operations without succumbing to wear and tear or incurring damage.
