What causes switch power supply due to silicone touch switch
The silicon gel touch switch filtering loss Pf includes the loss of the filtering inductor and the loss of the capacitor. If it is in continuous mode, the main loss is the coil loss, and the magnetic core loss can be ignored. The capacitor has a loss on the equivalent resistance Resr in series. In the continuous mode of the inductor, the ripple current of the capacitor is small, and the capacitor loss is also small. The entire filtering loss is approximately less than 1% of the output power. If it is an inverse-boost transformer, the Resr loss of the capacitor increases significantly, and the filtering loss is the capacitor loss.

How to choose a silicone touch switch
For the silicone touch switches, when purchasing, you should also weigh each individual switch to determine its weight. This is because only when the copper sheet inside the switch is thick will the weight of the single switch be significant. The copper sheet inside is the key part of the switch. If it is made of alloy or a thin copper sheet, it will not have the same weight and quality. When choosing silicone touch switches, consider the brand. We encourage everyone to choose well-known brands. Because the quality of the switch is related to the normal operation of the appliance and even the convenience of life.

What market conditions should connector manufacturers pay attention to
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

Common problems with connectors
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.
