Signal indicator light, a device that uses light to monitor the working or position status of circuits and electrical equipment. It is also the most intuitive and unique monitoring component in automation equipment. The main function is usually used to reflect the working state of the circuit (with or without electricity), the working state of electrical equipment (running, outage or test) and position state (closed or disconnected), etc. To remind the operator to deal with the fault in time, or operate a certain function to complete the relevant action.
Push button switch, also known as control button (referred to as button), is a low-voltage electrical appliance that can be manually reset and generally automatically reset. Buttons are usually used in circuits to issue start or stop commands to control the on and off of electric coil currents such as electromagnetic starters, contactors, and relays.
Main functions: generally used in control circuits with AC and DC voltages below 440V and currents less than 5A, generally do not directly manipulate the main circuit, but can also be used in interconnected circuits. In order to control the operation of the equipment, stop, pause or reset and other functions.
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.

Introduction: 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. Button switch real type
There are many types of button switch structures, which can be divided into ordinary push button type, mushroom head type, self-locking type, self-resetting type, rotary handle type, indicator light type, light symbol type and key type, etc. There are single button, Double buttons, three buttons and different combination forms generally adopt building block structure, which is composed of button cap, return spring, bridge contact and shell, etc., usually made into a composite type, with a pair of normally closed contacts and normally open contacts , Some products can increase the number of contact pairs by connecting multiple components in series. There is also a self-holding button that automatically holds the closed position after being pressed, and can only be opened when the power is turned off.
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.
