The 8-way lock electronic switch circuit is composed of the regulator filter circuit, input control circuit, latch circuit and control implementation circuit, and the circuit is shown as the chart. Regulator filter circuit is composed of the three terminal voltage regulator integrated circuit IC1 and filter capacitors C1, C2. Input control circuit consists of the control buttons S1 ~ S8, diodes VD1 ~ VD16. Latch circuit consists of eight D flip-flop integrated circuits IC2 and reset button S9, resistors R9 and R10, capacitor C3. Control implementation circuit is composed of the transistors V1 ~ V8, diodes VD17 ~ VD32, resistors R1 ~ R8 and relays K1 ~ K8. R1 ~ R10 uses 1/4W carbon film resistors or metal film resistors.
