[0002] An emergency switch is an emergency cutting device applied to scenarios such as engineering vehicles, buildings, or computer rooms, and is used to cut off the circuit in case of an emergency to ensure safety. When an accident or other emergency occurs, the emergency switch will quickly cut off the circuit to prevent further damage to electrical equipment and reduce accident injuries.

[0003] Existing emergency switches are set to be able to be opened or closed at will. Although this can timely switch the state of the emergency switch, it also brings some potential safety hazards to the operation of the circuit. For example, when the load end of the circuit is operating smoothly and the circuit is suddenly cut off, it may cause damage to the load equipment, and in more serious cases, it will also cause relatively large economic losses. Therefore, the existing emergency switches have reduced safety in use due to their ability to be switched at will, which is not conducive to long-term use. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the existing emergency switches have reduced safety in use and are not conducive to long-term use due to their ability to be switched at will.
