how to wire a 4-pin toggle switch

1．Definition of the 4-pin toggle switches

4-pin toggle switch is an electrical device commonly used to manage the state of a circuit, turning it on or off as needed. Its name comes from its unique mode of operation, which involves lightly flicking a lever back and forth. Typically, a toggle switch is composed of a lever, a mounting bracket for fixed switches, and one or more sets of electrical contacts.

When the switch is in the “on” position, the circuit is closed, 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. This 4-pin toggle switch is commonly used in various electronic and electrical applications, and 4-pin toggle switch play an important role in electronic and electrical engineering. They can be used for controlling the on-off state of a circuit, selecting between different circuits, adjusting circuit parameters, and more. With the continuous development of technology, the types and functions of toggle switches are constantly increasing to meet the changing market demand.

2．Types of 4-pin toggle switches

A 4-pin toggle switch is an electronic component commonly used to control circuit switching. Depending on different classification standards, 4-pin toggle switches can be divided into several common types:

Locking 4-pin toggle switch: This type of toggle switch requires the button to be pressed and rotated to turn on or off the circuit. They are usually used in circuits that need to avoid accidental shutdown.

Momentary 4-pin toggle switch: This type of toggle switch will bounce back after being pressed and will automatically return to its original position when the button is released. They are usually used in circuits that require frequent on-off switching.

Latching 4-pin toggle switch: This type of toggle switch will remain in the pressed position until it is pressed again to release it. They are usually used in circuits that require a specific position to be maintained.

Spring return 4-pin toggle switch: This type of toggle switch will only remain in the pressed position briefly and will immediately return to its original position when released. They are usually used in circuits that require a brief trigger.

Toggle switches generally have the option of being either through-hole or screw-mounted. Through-hole and screw-mounted are both forms of electrical components used for fixing and connecting circuits.

Through-hole is an electrical component that is fixed and connected to a circuit board by inserting pins into holes on the board. They are typically available in single-row, double-row, and triple-row configurations. Through-hole pins are fixed and connected to the circuit board through friction and pressure, and are characterized by their easy installation and reliable connection.

The advantages of through-hole pins are their simple installation and reliable connection, making them suitable for applications that require easy installation, small size, and frequent connections. The disadvantage of through-hole pins is that the connection strength is weaker and more prone to loosening, making them unsuitable for applications that require high connection strength. Additionally, since through-hole pins need to be inserted into holes, they cannot be directly fixed to the circuit board and require other methods of fastening.

Screw-mounted toggle switches are electrical components that are fixed to a circuit board using screws. They are available in a variety of types, including round head, flat head, and semi-circular head. Screw-mounted toggle switches are fixed to the circuit board using screws, making them easy to replace, disassemble, and repair as needed.

The advantages of screw-mounted toggle switches are their strong connection, replaceability, and ease of disassembly, making them suitable for applications that require reliable connections and easy replacement. The disadvantage of screw-mounted toggle switches is that installation and disassembly require tools such as screwdrivers, making them relatively more complicated to use than through-hole pins.

3．Structure of the 4-pin toggle switches

Housing: The housing is usually made of plastic or metal and is used to protect the internal components, improve mechanical strength, and increase durability.

Lever: The lever is typically made of metal and is used to manually toggle the switch to connect or disconnect the circuit.

Contacts: The contacts are typically made of metal materials such as copper or silver and are used to make and break the electrical connection.

Springs: The springs are typically made of metal materials and are used to control the opening and closing of the contacts.

Mounting bracket: The mounting bracket is typically made of plastic or metal and is used to fix the lever and contacts of the switch in place.

Terminals: The terminals are typically made of metal materials and are used to connect the switch to the circuit.

These components work together to form the internal structure of a toggle switch. When the lever is moved, the contacts make or break the electrical connection, allowing current to flow or preventing it from flowing through the circuit. The housing and mounting bracket provide protection and support for the internal components, while the terminals provide a means of connecting the switch to the circuit.

Waterproof cap:

A small plastic or rubber cap used to protect electronic components from water, dust, corrosion, and other environmental factors. It is typically placed on the component terminals to protect them from external damage.

Toggle switch cover:

It is usually a cover-shaped component that is installed on a toggle switch to cover the operating part of the switch, providing protection and preventing the operating part from being impacted or damaged by external objects.

The design of toggle switch covers typically takes into account the size, shape, and operation of the switch, ensuring that the cover fits tightly over the operating part of the switch and is perfectly compatible with the switch itself.

4.How to wire a 4-pin toggle switch

First, prepare a battery, a four-pin toggle switch, and two devices.Connect the positive terminal of the battery to one of the ON pins of the toggle switch.Connect one of the OFF pins of the toggle switch to one side of one of the devices.Connect the other side of the device to the negative terminal of the battery.Next, connect the positive terminal of the battery to the other ON pin of the toggle switch.Connect the other OFF pin of the toggle switch to one side of the other device.

When you toggle the switch, the switch will close, and both devices will turn on and start working. When you toggle the switch again, the switch will open, and both devices will turn off and stop working.
