Wiring problem with button switch
1. How to wire the button switch with light. There are five terminals on the button. Now I can only measure how to connect the power line, but I don’t know how to connect the light.
Answer: This situation is relatively simple. This kind of switch should have two terminals connected to the light, and the other three terminals are for switches. Find out the terminal connected to the light and the terminal of the switch, and then distinguish which two terminals you want to use to connect Switch, directly connect the light and the switch terminal to be connected in series, so that when the switch is turned on, the light will be on.

A push button is a manually controlled master electrical appliance. It is mainly used to issue operation commands, turn on or off the control circuit, and control the operation of mechanical and electrical equipment. The working principle of the button is very simple. For the normally open contact, the circuit is disconnected before the button is pressed. After the button is pressed, the normally open contact is connected and the circuit is also connected; for the normally closed contact, Before the button is pressed, the contacts are closed, and when the button is pressed, the contacts are opened and the circuit is broken. Due to the needs of the work of the control circuit, a button can also have multiple pairs of contacts that act simultaneously.
Buttons have a wide range of uses, such as starting and stopping of lathes, forward rotation and reverse rotation, etc.; start, stop, rise, fall, forward, backward, left, right, slow or fast operation of tower cranes, etc., all need buttons control.
The push button switch refers to a switch that uses a button to push the transmission mechanism to make the moving contact and the static contact press on or off and realize the circuit switching. The push button switch is a kind of master electrical appliance with simple structure and wide application. In electrical automatic control circuits, it is used to manually send control signals to control contactors, relays, electromagnetic starters, etc.
A button is a control switch that is operated by applying force from a certain part of the human body (usually a finger or palm) and has a spring energy storage reset. It is the most commonly used master electrical appliance.
The current allowed to pass through the contact of the button is relatively small, generally no more than 5A. Therefore, under normal circumstances, it does not directly control the on-off of the main circuit (high current circuit), but sends an instruction signal in the control circuit (small current circuit) to control electrical appliances such as contactors and relays, and then they
When the button is under the action of external force, the opening and closing state of the contact changes.
Buttons are ubiquitous in our daily lives, serving as a critical interface between humans and technology. These small yet powerful devices are used to activate a wide range of functions, from turning on a light switch to launching a rocket into space. In this article, we will explore the functions and manufacturing process of buttons.
Function of Buttons:
Buttons are used to initiate a specific function or operation. They can be simple or complex, ranging from a basic on/off switch to a multifunctional keypad. Some common examples of button functions include:
Power on/off: A button is used to turn on or off an electronic device.
Volume control: Buttons are used to adjust the volume of a device, such as a speaker or TV.
Navigation: Buttons are used to move through menus and select options on a screen.
Input: Buttons are used to enter data, such as letters or numbers, into a device.
Buttons can be found in a wide range of devices, including smartphones, computers, cars, and household appliances. They are designed to be easy to use and reliable, ensuring that users can interact with technology in a seamless and intuitive way.
Manufacturing of Buttons:
The process of manufacturing buttons involves several steps, including design, molding, and assembly. Here are the typical steps involved in creating a button:
Design: The first step is to create a design for the button. This involves deciding on the size, shape, and color of the button, as well as any symbols or text that will be included.
Mold making: Once the design is finalized, a mold is created using a special material, such as steel or aluminum. The mold is shaped to match the desired size and shape of the button.
Injection molding: The mold is then filled with a special material, such as plastic or rubber, and heated until it solidifies. This process is known as injection molding, and it allows for precise and consistent production of buttons.
Assembly: Once the button has been molded, it is ready for assembly. This involves attaching any necessary components, such as springs or circuits, and testing the button to ensure that it functions properly.
Overall, buttons are an essential part of our daily lives, and they are manufactured using a complex and precise process. With their wide range of functions and designs, buttons will continue to play a critical role in how we interact with technology for many years to come.
Metal button switch (push-buttons switch) refers to a switch that uses a button to push the transmission mechanism to make the moving contact and the static contact press on or off and realize the circuit switching. The metal push button switch is a master electrical appliance with a simple structure and a wide range of applications. In electrical automatic control circuits, it is used to manually send control signals to control contactors, relays, electromagnetic starters, etc.
With the rapid development of microelectronics technology, the control technology is becoming more and more perfect and mature. As the core component of industrial control, the metal button switch has more and more powerful control functions, smaller and smaller volume, and more high-speed and reliable operation. ; The human-machine interface (HMI) has completely broken the traditional operation modes such as buttons and signal lights, making the equipment operation interface more popular, friendly, flexible and diverse, and its powerful storage function and communication capability have brought difficulties to equipment manufacturers and users. It is the general trend to replace the traditional equipment operation interface with the desired benefits and convenience; the control technology of the frequency converter used for ordinary motor speed regulation has far exceeded the early single metal button switch control method, and is rapidly moving towards sensorless The development of vectorization and direct torque control has made it widely used in various industries.
