How to develop (and print) a PCB starting from a logic scheme
First, consider which logic family you intend to use:

What DC power supply is available? Some families are fussy (TTL requires +5V) while others are more tolerant (HCmos runs from +3V to +6V), (COSMOS from +3V to +18V).

What load must be driven? Your pseudo-schematic shows a lamp as load. An incandescent lamp would require more current than most logic could supply. A LED could be driven more easily by most logic families, with a series resistor.

How are logic inputs generated? Switches for this static design are simple, good input devices and won't need de-bouncing. But pull-up or pull-down resistors will be required. Resistor value depends on the logic family you choose.


Once a logic family is chosen, choose small-scale-logic chips from that family. You have some 2-input NAND gates, some 3-input NAND gates and one 4-input NAND gate. You'd like to use as few chips as possible.
For example, in TTL logic family, a 7400 chip contains four 2-input NAND gates. This one chip could fill the requirement for the four switch input inverters.
You also need four 3-input NANDs. A 7410 only contains three three-input NANDs. Do you need another 7410 for the fourth gate?
A hint: you only need three physical TTL chips to build this circuit, should you choose the TTL logic family.

Logic input:
Four Single-pole single-throw switches (SPST) can be used to generate logic high and logic low for this design:

It is better that an "activated" switch generates a logic low rather than logic high. In the schematic, all switches are shown "not-activated" - that is: open circuit. The associated 1k pull-up resistor generates a logic high in this case. When the switch is closed, the logic gate input is grounded, generating a logic low.
At the output, a logic gate drives a LED indicator. The series resistor value affects the LED brightness - a smaller-value resistor increases current and therefore brightness. The LED will light when logic output goes &quot;low&quot;.

Consider building this circuit on a breadboard, to gain experience and confidence. Then attempt a printed circuit.
Remember that these schematics do not show supply connections, because they would add needless clutter. However, each logic chip you use has &quot;Vcc&quot; or &quot;Vdd&quot; supply pin, and a &quot;GND&quot; pin that must be wired to the DC supply. All logic should see the same DC supply: in the TTL examples shown here, this would be +5V.
