Power relays are essential components in electrical systems, responsible for switching high voltage or high current circuits through low-power control signals. They are widely used in a variety of applications, from industrial machinery to automotive systems. However, one of the most significant challenges that power relays face is contact welding. This issue occurs when the contacts of the relay stick together due to the heat generated by excessive current or electrical arcing. Contact welding can result in relay failure, circuit malfunction, and potentially even safety hazards. Therefore, understanding and implementing effective solutions to prevent contact welding is crucial for maintaining the reliability and longevity of power relays.
