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.
Smart home devices: Push button switches can be integrated into smart home devices to control lighting, appliances, and other electronic devices.
Medical equipment: Push button switches are used in various medical equipment such as patient monitors, ventilators, and infusion pumps.
Industrial automation: Push button switches are used in industrial automation systems to control machinery and equipment.
Automotive: Push button switches are used in automotive applications such as power windows, power door locks, and engine start/stop buttons.
Push button switch factories are mainly located in the coastal areas of China, particularly in the provinces of Guangdong, Zhejiang, and Jiangsu. These provinces have a strong manufacturing base and are home to many electronics and electrical components manufacturers.
The key switch is a component widely used in electronic equipment, and China is one of the important bases of the global key switch manufacturing industry. Key switch factories are mainly distributed in the following places:
Dongguan City, Guangdong Province: Dongguan City is one of the regions with the most developed key switch industry in China, and has a large number of key switch manufacturers and supporting enterprises.
Wenzhou City, Zhejiang Province: The key switch industry in Wenzhou City started earlier and has a relatively complete industrial chain. Among them, key switch enterprises represented by GQEM enjoy a high reputation in the industry.
Suzhou City, Jiangsu Province: Suzhou City is one of the important bases of China's electronic information industry, and has a group of professional key switch enterprises.
Shenzhen, Guangdong Province: Shenzhen is the center of the global electronic information industry and has a large number of electronic component manufacturers, including key switch manufacturers.
In addition to the above-mentioned regions, there are also many key switch manufacturers in Jiangsu, Zhejiang and Shanghai, Fujian Province, Shandong Province and other places.
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.
