Switch contact status with power indication device

Abstract

This invention relates to a switch contact status with a power indication device, which improves upon existing technologies that fail to accurately determine the internal contact status of low-voltage circuit breakers and display all power conditions, leading to misjudgments that affect electrical safety.The invention comprises a control power circuit, a switch contact voltage detection circuit, a voltage sensing unit, a current sensing unit, an analog-to-digital conversion unit, a microprocessor unit, a display unit, and an actuating output unit. This configuration enables clear identification of all circuit breaker statuses. The device is compact, cost-effective, complies with regulatory requirements, and enhances electrical safety.
