description The utility model discloses a switch type protective circuit for lithium batteries. The protective circuit comprises a plug circuit arranged in a plug and a socket circuit arranged in a socket. A positive electrode terminal A+ and a negative electrode terminal A- which perform electric conducting functions are arranged in the plug circuit. The positive electrode terminal A+ comprises two overhung pins P+/K. The socket circuit comprises a lithium battery protective IC (integrated circuit), a lithium battery, field effect transistors MOSFET1 and MOSFET2 and a current limiting resistor R. The positive and negative electrodes P+/P- of the lithium battery are overhung. The power pin VDD of the lithium battery protective IC is connected with the overhung K pin, the ground pin VSS of the lithium battery protective IC is connected with the negative electrode of the lithium battery, the overcharge detection output DO pin of the lithium battery protective IC is connected with the field effect transistor MOSFET1, and th
