How To Wire Toggle Button Switches

1、toggle button switches type

toggle button switch, also known as a switch, is an electronic switch. It usually consists of a button and a corresponding circuit. The button is typically composed of a spring and a movable contact. When the button is pressed, the contact touches the fixed contact, closing the circuit; when the button is released, the spring returns the contact to its original position, breaking the circuit. toggle button switches are commonly used in control circuits for electronic devices such as TVs, stereos, and computers.

toggle button switches are usually divided into different types such as single pole single throw, single pole double throw, double pole single throw, and double pole double throw. The difference between these types lies in the number and fixed position of the lever switch’s electrical contacts.

A single pole single throw switch has only one electrical contact and can achieve the on/off function of a single circuit. A single pole double throw switch has one electrical contact and two fixed positions, allowing the switching function between two circuits. It has one control electrode, one input electrode, and two output electrodes. When the switch is in one position, the input electrode is connected to one output electrode, and in the other position, the input electrode is connected to the other output electrode. This type of switch is usually used to control two different circuits, such as switching between left and right channels in an audio amplifier.

A double pole single throw switch has two electrical contacts and one fixed position, allowing the alternating switching function of two circuits. A double pole double throw switch has two electrical contacts and two fixed positions, allowing the alternating switching function between two circuits。

Common types of toggle button switches include ON-ON momentary switches and on off on toggle button switches.

ON-ON momentary toggle button switches usually consist of a lever and two electrical contacts, allowing for momentary switching between two circuits. When the lever is in one position, one circuit is connected and the other is disconnected; when the lever is moved to another position, one circuit is disconnected and the other is connected. ON-ON momentary switches are usually used to control the switching of electronic devices, such as switching between input sources and output devices.

On off on toggle button switches usually consist of a lever and three electrical contacts, allowing for switching between three circuits. When the lever is in one position, one circuit is connected while the other two are disconnected; when the lever is moved to another position, all circuits are disconnected; when the lever is moved to the third position, another circuit is connected while the other one is disconnected. ON-OFF-ON toggle button switches are usually used to control the selection of electronic devices, such as selecting different input sources and output devices.

In addition to the above types of toggle button switches, there are also some other types of toggle button switches, such as on off toggle button switch, OFF-ON, ON-MOM, OFF-MOM, etc. The difference between these toggle button switches lies in the number, type, and fixed position of the electrical contacts. Users can choose the appropriate switch according to their own needs.

An on off toggle button switch has only two electrical contacts and can achieve the on/off function of a single circuit. When the lever is in one position, the circuit is connected; when the lever is moved to another position, the circuit is disconnected. On off toggle button switches are usually used to control the on/off function of a single electronic device, such as turning a light, motor, or fan on or off.

An OFF-ON toggle button switch is similar to an ON-OFF switch, with only two electrical contacts, but the circuit’s switching function is opposite to that of an ON-OFF switch. When the lever is in one position, the circuit is off; when the lever is moved to another position, the circuit is on. OFF-ON switches are also usually used to control the on/off function of a single electronic device.

A toggle light switch usually has a built-in LED indicator light, which lights up when the circuit is turned on, allowing the user to visually perceive the state of the switch and determine whether the circuit is working properly. toggle button switch with light can be manufactured in different voltage levels, such as 120V or 12V toggle button switch, with 12V voltage being the main one. lighted toggle button switch is important to choose the appropriate voltage level that matches the circuit when using it, as using the wrong voltage level may cause the switch to malfunction or burn out. 12V toggle button switches can also be manufactured in different LED colors, such as red, green, yellow, blue, and white. Blue lighted toggle button switches are the most popular color, and green toggle light switches are also a good choice because they are brighter, easier to identify, and can clearly indicate the switch’s status.

Waterproof lighted toggle button switches, such as those produced by FILN, are the world’s first push button switches to feature waterproofing and LED lighting. They come in different installation hole sizes, such as 16mm, and the back of the toggle button switch is coated with glue so that it can be submerged in water and has excellent waterproofing capabilities. They can also be manufactured in different LED colors, such as red, green, blue, and white, to meet the different color needs of users, and can be customized to be single-color or dual-color according to requirements. They are widely used in various fields such as automobiles, yachts, and underwater operations.

In practical applications, different types of lever switches can be selected according to the desired control function.For example, a single pole single throw switch is usually used to control the on/off function of a single circuit, such as turning a light or motor on or off; a single pole double throw switch is usually used to select different circuits, such as selecting different input sources or output devices; a double pole single throw switch is usually used to alternate the control of two circuits, such as alternating the control of two lights or motors; and a double pole double throw switch is usually used to alternate the selection of two circuits, such as alternating the selection of two input sources or output devices.

2、How the switch works?

The working principle of a toggle button switch is based on the principle of mechanical contacts. When the button is pressed, the spring inside the button moves it from the released position to the pressed position, causing the movable contact on the button to touch the fixed contact, thus forming a circuit. When the button is released, the spring returns the button to the released position, causing the movable contact on the button to separate from the fixed contact, thus breaking the circuit.

The mechanical contacts of a toggle button switch are usually made of metal materials such as copper and silver, which have good conductivity and mechanical strength and can withstand thousands of pressing operations. When the button is pressed, the movable contact touches the fixed contact, forming a low-impedance circuit; when the button is released, the movable contact separates from the fixed contact, cutting off the circuit. This design of mechanical contacts makes toggle button switches have good electrical performance and mechanical reliability, and therefore, they are widely used in many electronic devices.

It should be noted that since the mechanical contacts of toggle button switches are made of metal materials, long-term use may cause problems such as contact oxidation and wear, leading to a decrease in electrical performance or even failure. Therefore, when using toggle button switches, it is important to choose suitable quality and service life and to carry out appropriate maintenance.

3、composition and structure

Generally, the components of a toggle button switch include the following:

1、Housing: The housing is usually made of plastic or metal materials and is used to protect the internal components and provide support for installing and fixing the switch.

2、Toggle lever: The toggle lever is the component used to control the switch status and is typically presented in a rod shape that can be switched between two or more positions.

3、Three pins: The led toggle button switch typically has three pins, one for connecting to the power supply positive, one for connecting to the device positive, and the third for connecting to the control line of the circuit.

4、Internal circuit: The internal circuit of the switch is the key part that controls the switch status. They are usually composed of metal conductors and semiconductor devices such as diodes and transistors.

5、LED indicator light: The 12v 3 position toggle button switch is also equipped with a built-in LED indicator light to display the switch status, such as RED LED toggle button switch, GREEN LED toggle button switch, YELLOW LED toggle button switch , and BULE LED TOGGLE SIWTCH. These indicator lights are usually composed of LED chips, resistors, and wires. When the switch is in the open state, the LED indicator light will light up, indicating that the circuit is working normally; when the switch is in the closed state, the indicator light will go out, indicating that the circuit has been disconnected.

6、Contacts: The contacts of the car toggle button switch are the key components that control the switch status. They are usually made of metal materials and undergo special treatment to improve their wear and corrosion resistance. When the button is pressed, the contacts will connect or disconnect the circuit, thereby controlling the operation of the device.
