20KV Reed Relay

A 20kV high voltage reed relay is a specialized electromechanical switch designed to handle high voltage applications up to 20,000 volts. These relays use a reed switch mechanism, where two ferromagnetic reeds are hermetically sealed within a glass tube containing inert gas. When a magnetic field is applied, the reeds make or break contact, allowing or interrupting the flow of current.

Introduction:
