In the graph, K can adopt JZC-22F, DC12V miniature electromagnetic relay. The coil resistance is 400, and contact capacity is 5A. VT1, VT2 require using type 9013 transistor whose performance should be as consistent as possible. Beta value is about 100. Note: VT1 beta value cannot be greater than VT2, otherwise the circuit can not work normally.
