The triple-layer composite contact is an important component commonly found in electrical devices and circuits, used to establish or interrupt electrical connections. It combines the functions of three independent contacts and is usually made of materials with good conductive properties to ensure reliable electrical contact. The triple-layer composite contact plays a key role in various applications, such as relays, circuit breakers, switches, and more. Below, I will provide a detailed introduction to the working principle, structure, performance characteristics, and applications of the triple-layer composite contact.

Working principle：

The basic working principle of the triple-layer composite contact is to utilize three independent contacts to simultaneously establish or interrupt electrical connections under the action of external pressure or electromagnetic force. When external pressure or electromagnetic force is applied, the three contacts of the triple-layer composite contact will come into contact with the corresponding contact objects, forming a circuit connection. Through this mechanism, a more reliable electrical connection and more stable circuit transmission can be achieved.

Structure：

The triple-layer composite contact typically consists of three independent contacts, each made of conductive materials such as copper or silver alloys. These contacts are connected together through a supporting structure to ensure that they move simultaneously when subjected to external forces. The structural design of the triple-layer composite contact is aimed at providing higher reliability and stability, while ensuring good electrical contact.
