The invention relates to a switch socket with an automatic fire extinguishing bomb, comprising a switch socket, and an automatic fire extinguishing bomb, and characterized in that the panel of the switch socket is provided with the automatic fire extinguishing bomb projecting outwardly; the automatic fire extinguishing bomb is equipped with fire extinguishing dry powder; a push plug is arranged behind the automatic fire extinguishing bomb, and is next to the projection of an elastic arm arching in the push plug direction. Meanwhile, the elastic arm is in contact with an outage contact. When the automatic fire extinguishing bomb explodes, the fire extinguishing dry powder therein extinguishes the combustion source nearby; meanwhile, recoil generated by explosion drives the push plug to eject the salient point of the elastic arm, thereby rapidly interrupt power supply. The switch socket has the characteristics of ingenious conception, simple structure, low cost and high practicality, provides a new guarantee scheme for electricity safety, and can substantially reduce fire rates.
