Abstract

The invention relates to a direct-current switch comprising a relay and a relay control module. The relay control module comprises an MCU which is in control connection with a coil of the relay and is sampling connection with a current sensor and a voltage sensor. The current sensor is used for measuring the current flowing through a contact loop of the relay, and the voltage sensor is used for measuring the input voltage of the direct-current switch. The current state and voltage state of the direct-current switch can be visually monitored in real time, so that the operating state of the direct-current switch can be known visually, and furthermore, the power consumption can be calculated based on the voltage and current values.

Description
