AI Technical Summary
Existing communication switches cannot cut off power in a timely manner when network conditions are poor or the network is down, which limits their use.
A communication switch was designed, comprising a housing, a terminal block, and a circuit board. The circuit board has a disconnect circuit, which is electrically connected to the connection terminal via a disconnect button, enabling forced power cut-off when the network is poor.
In situations with poor network connectivity, the forced disconnection function can be achieved through close-range operation, ensuring reliable power cut-off and enhancing the practicality of the communication switch.
