The invention discloses a furnace body switching switch for an intermediate frequency induction melting furnace, which includes two sets of furnace cables connected to copper bars, one set of capacitor cables connected to copper bars, and two sets of compaction systems. Two copper bars, one set of capacitor cable connection copper bars are composed of two copper bars that are insulated from each other. Each set of compaction system is composed of two compaction devices, each of which includes a hydraulic cylinder and a hydraulic cylinder plunger. The universal ball head, the connection plate, the insulation plate and the conductive plate are connected in that order. The hydraulic system controls the cable connection copper bar and capacitor cable connection copper bar of one of the furnace bodies in a working state through two sets of compaction systems, and the other furnace body is in a safe and non-electric state. , Safe and reliable, can improve work efficiency.
