Relaxation oscillator is composed of unijunction transistors BT33、C3、W1、W2 and some other components, the produced pulse singal is transported to control pole of SCR1 by isolating diode D4, the trigger conduction angle of SCR1 can be changed by adjusting W1's resistance, it also changes the changing current. Storage battery fully charge automatic protection circuit is composed of SCR2, relay J, W3, W4, D5 and some other components, when the voltage on both sides of battery is charged to the upper limit which is set by W3, W4, then D5 turns on, SCR2 is triggered to turn on, LED2 displays, relay pulls in, J is switched to normally open, it cuts off SCR1's control pulse integrating, it stops charging to storage battey. K2 is the transfer switch of 12V, 24V changing batteries, as shown in the figure, it is in 12V gear.
