For example, the main supporting industries of electronic connectors include transportation, communication, internet, healthcare, household appliances, etc. The development of electronic products has also promoted the development of connectors, and at the same time brought a large amount of profit space for connector suppliers. Up to now, connectors have developed into products with a wide variety of types, complete specifications, diversified structural types, segmented professional directions, and distinct industry characteristics. Generally, the development of connector technology has the following features: higher signal transmission rate

The metal conductor inside the poor-contact terminal is the core component of the terminal. It transmits the voltage, current or signal from the external wire or cable to the corresponding contact piece of the connector that matches it. Therefore, the contact piece must have excellent structure, stable and reliable contact holding force, and good conductivity. Due to unreasonable design of the contact piece structure, incorrect selection of materials, unstable molds, processing size deviations, rough surface, unreasonable surface treatment processes such as heat treatment and electroplating, and improper assembly, etc.

Imported push-button switches are widely used in various fields. Common examples in daily life include Bluetooth headphones, automotive electronics, wearable devices, mobile phones, medical equipment, tablets, Bluetooth keyboards, computer peripheral products, and so on. The reason why the application scope of imported push-button switches is so extensive is because imported push-button switches have the following several advantages. Advantage 1: They have a long lifespan, high precision, good feel, excellent oxidation resistance, strong temperature resistance, low-temperature resistance, and extremely high stability.

A four-foot touch switch, as the name suggests, refers to a touch switch with four feet. Four-foot touch switches are commonly used in daily products and account for a significant portion of them. Here, the "four feet" refers to the four pins of the touch switch. These four pins consist of two groups of switches. When pressed, both groups are powered simultaneously, and when released, both groups are powered separately. Some people say that these four pins are used to ensure a firm connection of the circuit board. In fact, this understanding is also correct.

The new generation of photoelectric switch equipment, which is manufactured by using integrated circuit technology and SMT surface equipment technology, is a kind of intelligent photoelectric switch with functions such as delay, expansion, external synchronization, anti-interference, high reliability, stable working area and self-diagnosis. This novel photoelectric switch is an active photoelectric detection system-type electronic switch that uses pulse modulation. The cold light sources it employs include infrared light, red light, green light and blue light, etc. It can non-contact and non-destructively sensitively and controllably monitor the conditions and movements of various solids, liquids, transparent bodies, black bodies, soft bodies and smoke, etc.
