OK so I have this circuit I am working on and I will describe what it is because I don't have a photo at the moment.
Anyway I have a 12V power that runs into a Normally Open side of a DPST switch and then a 3.25V power that runs into the switch on the normally Closed side of that switch/ these exit via the common so that it will send either 12V or 3.25V depending on the switch position.
The single line from the switch is connected to two triggers one for the 12V line and one for the 3.25V.
The issue I am having is that the 12V trigger of course is always being fed with at least 3.25V since when the switch is Normally Closed on the DPST 3.25V is always being fed and ONLY when the Switch goes Open does the voltage increase to 12v and the 3.25v line and trigger gets deactivated. That 3.25V always going to the 12V trigger is actually enough to Keep it active or on.
I know the simple way to do this would be to have a DPDT through and switch the ground as well but I don't have that luxury at this moment due to design constraints. so what I was hoping to do was to find out if there is a way that I can put some sort of element between the 3.25V trigger and the 12V trigger that would actually block the voltage flow to the 12V when the voltage was lower than a certain level.
I thought about a 8V Zener Diode and tried it physically in both polarity and it didn't work as I was thinking that in reverse polarity it would totally cut off the flow below 8V..
Im not super experienced with electronics but know enough to get myself into trouble but generally not fry stuff lol.. Any help would be appreciated
