Hello there everyone, I’m working on some exhibit that I should hand in at the end of the month. In that model I have 8 Switches and 8 Loads each load id a 12V led stripe.

The problem is that it’s not 1 load per switch but the design demand that some switches will power all of the loads. The problem is of course that I short circuit all the connection so all the loads will power in response to every switch.

I know why but nor sure how to solve it. I understood that I should either use diodes not sure how and whether it needs more element like resistors or so or a digital circuit. I would like to implement the “diode” solution in case that the voltage drop on the diode wont cause a voltage that would be too low on the led stripe.


In case there is no other solution I’ll just get another adapter. In addition, if it’s not too much to ask, I’d love to see a smarter solution with digital circuits in order to learn. I did search the forum before but had some hard time finding posts with the same subject or that would even be related because i couldn’t define my need well enough. Any explanation link, scheme, guidance.

Describe what you want if this isn’t it. May 8, 3. Thanks for your reply. The circuit you designed isn’t what I need for the exhibit. I guess I wasn’t understood-able. The functionality I need is: May 8, 4. May 8, 5. Nov 3, 1, Draw 8 vertical line’s with a switch at the top of each, then draw 8 horizontal lies with a load at the right end on each of those lines. Continue with other switches. Can later if need be. May 8, 6. A drawing would help a lot actually.

I must have not understand because a 2 Switch 2 Loads simulation I made did not run as expected. May 8, 7. Aug 23, 6, You will need to do like this: May 8, 8.


Hi ScottWang, thanks for your answer. I dstasheet the specs of the OR gate you attached and it support a max Vcc of 7V only was looking for a 12v one but only found dual 4input and gate for that voltage. In addition can you please explain why is the resistor needed and especially why do i need xatasheet use a transistor can’t i just short that last input to GND in that 4-input-or-gate?
