Different characteristics of metal buttons made of stainless steel and aluminum alloy
Stainless steel: Stainless steel has the characteristics of high strength, corrosion resistance, and high temperature resistance. It is one of the commonly used materials for making metal buttons.
Aluminum alloy: The aluminum alloy material has the characteristics of lightness, high strength, and good thermal conductivity, and is often used to make metal buttons.
Copper: Copper has good electrical and thermal conductivity, and has a beautiful appearance. It is often used to make high-end metal buttons.
Brass: Brass has good machinability and corrosion resistance, and is golden in color, and is often used to make metal buttons.
Titanium alloy: Titanium alloy material has the characteristics of high strength, light weight, and corrosion resistance. It is a high-grade metal button material.
The above are the main materials of metal buttons switch. Metal buttons of different materials are different in appearance, performance and price. Choosing the right material can be considered according to specific application requirements and cost budget.

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.
Circuit breakers, contactors, intermediate relays, thermal relays, buttons, indicator lights, universal transfer switches and travel switches are the eight most common components in electrical control circuits. The editor introduces the principles and applications of common electrical components with pictures and texts. Get a handle on how these components work in normal times by understanding their role in the electrical circuit.
1. Circuit breaker
Low-voltage circuit breakers are also called automatic air switches, which can be switched manually, and can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. Automatically cut off the circuit.

2. Contactor
The contactor is composed of two parts, the electromagnetic mechanism and the contact system. The common coil voltages of the contactor are AC220V, AC380V and DC220V. The electromagnetic mechanism of the contactor is composed of a coil, a moving iron core (armature) and a static iron core; the contactor contact system is composed of two parts, the main contact and the auxiliary contact, the main contact is used to switch the main circuit, and the auxiliary contact is used to control in the circuit.

Button control principle with Gqele
Definition: A switch that uses a button to push the transmission mechanism to make the moving contact and the static contact on or off and realize the circuit switching.
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.
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.
