The Electrical Contacts and Copper Terminal are one of the key components of the electrical appliance. The main performance and lifespan of the switching electrical appliance depend to a large extent on the quality of the contact material. How does it work? Today, let's take a look at how the electrical silver contacts realize the switching process. The following is a specific analysis:

1. Electrical contacts: separation process. When the Silver Electrical Contacts begin to separate, the moving contacts move in the direction of separation from the stationary contacts. During this stage of operation, the circuit is not broken, but the overtravel and Silver Contact Points pressure are gradually reduced, and the contact point is gradually reduced until the last contact point remains. The current density at this point of Silver Electronic Contact is very high and the temperature rises sharply, so the Silver Alloy Electrical Contacts melts.

2. Bimetal Contact Rivets: form a liquid metal bridge and break it. Since the resistance of the metal bridge is greater than that of the solid metal, relatively high heat is accumulated in the bridge at this time, causing the temperature of the metal bridge to reach the boiling point, and then the metal bridge bursts explosively, forming a contact gap.

3. Bimetallic Contact Rivet: The silver contact is disconnected to form an arc. When the Bimetallic Silver Contacts open, the gap is filled with metal vapor and air. Since the current is cut off immediately, an overvoltage is created, which destroys the air medium and metal vapor, and creates an arc.
