The subject innovation is a circuit relates to a learning machine, in particular a light emitting diode piezoelectric buzzer, a capacitor, a resistor, but printing on a variety of electrical parts sign surface of the electronic device, such as a push switch, the component symbol edge is forming a terminal connection hole, and one side of the coil spring engaged with the circuit box hayeoseo form a part coupling hole, the another part of the to be connected respectively to a circuit learning machine composed of a an elastic body coupled to the terminal connection hole of the circuit box coil spring to a terminal connection hole by the next yawn tilts the lower or upper side to side ever connected in a very simple way fitting the terminal wires or components, circuits, learning when principles, so you do not have to solder as the existing easy to avoid any risk of accident safety circuit It will have to learn.
