Electrical contacts
Electrical contacts are the points where two conductive surfaces meet to allow the flow of electrical current. They are found in switches, relays, circuit breakers, and connectors. When the contacts touch, electricity passes through; when they separate, the circuit is broken. Proper contact design ensures reliable operation, minimal resistance, and durability. Factors like surface finish and material choice affect performance and longevity, preventing issues such as arcing or corrosion. In essence, electrical contacts serve as the critical switching interface in electronic and electrical systems, enabling controlled energy transfer.
