# Multi-AND circuit

I want to build a circuit with multi AND logic which may trigger different LED by different combination of switch

Here is my thought:

simulate this circuit – Schematic created using CircuitLab

So when I press 1,2,4 it will trigger one LED and 1,3,4 for another
But I don't know how to achieve this since it might trigger both LED with those combination

So how can I have different switch combination to trigger different LED but with same switches?

• Press sw2 and sw5 means both lights on, 3 and 4 no function – Solar Mike Aug 8 '17 at 10:50
• You press 1,2,4 ... Where is 1? – Bart Aug 8 '17 at 10:58
• Oops sorry plus one to all the numbers to match the switch – Andrew Young Aug 8 '17 at 11:01
• The polarity of your battery is reversed. If it is not a typo, when you apply the voltage to the LEDs you could fry them. Most common LEDs have a max reverse voltage of about 6V~8V. – Lorenzo Donati Aug 8 '17 at 11:36
• You should edit the question, not fix it in the comments. – Bart Aug 8 '17 at 11:50
