A rocker switch having a sliding and pressing element, comprising a thermal conductive shell and an overheating destructive element. The sliding and pressing element is applied to the rocker switch. The overheating destructive element can be destroyed at a destructive temperature, and the destructive temperature is between 100 C. to 250 C. The thermal conductive shell is pressed against a rocker conductive element of the rocker switch so as to control the rocker conductive element to be electrically connected or electrically disconnected. When the rocker conductive element is electrically connected, and if the overheating destructive element is overheated and destroyed, the rocker conductive element would be electrically disconnected, thereby realizing protection from overheating. The overheating destructive element is tightly adhered to the thermal conductive shell and is capable of completely absorbing a heat energy generated by a circuit, thus giving the element the advantage of high sensitivity.

A miniature circuit breaker with quick current breaking capability which includes a miniature circuit breaker body, a current transformer CT1, a zero-sequence current transformer CT2 and a smart controller module. The miniature circuit breaker body is internally provided with a main arc extinguishing chamber, a fixed contact, a movable contact, a tripping mechanism, and a magnetic tripping push rod. The tripping mechanism includes a lock catch, a movable contact rocker arm, a jump pin, a connecting rod, and a tension spring. A rotated-hinge repulsive force structure is applied between the fixed contact and the movable contact. The tripping mechanism is further provided with a torsional spring to press the movable contact close to the fixed contact. A shunt tripping device controlling the miniature circuit breaker switch to be turned off is arranged in the smart controller module.

The circuit breaking system contains a power circuit whose voltage is greater than 600 volts, at least a circuit breaking device, at least a current detection device, a current reduction unit, at least an actuation device, and a linking device. The circuit breaking system is applicable to a high or ultra-high voltage power circuit, and the power circuit is interrupted through purely mechanical means without additional electricity provision. Even when there are major disasters that existing protection means fails, the present invention can still function and provides a trip free, ultimate self-protection mechanism so that a power system can be readily reset.
