Okay so once I got the correct transistors installed (the package was labeled wrong) the circuit works okay except that it seems to require a second or two between button pushes to change state. If I push the button to quickly, it does nothing untill I give it a second or two and then push the...
Okay so I built this thing up last night and tried it at 12 and 24 volts and nothing worked. So I went back over everything this morning and all is correct. I started checking voltages in various places and found that all three transistors appear to be partially conducting all the time. I even...
I see what you're saying about the relative versus absolute voltage. So if I do build it and run it as is with a 24-28V source, the circuit will work with a 24V relay coil that draws maybe 50ma?
I need to control a simple relay with a push button; push on/push off. I found this circuit online which seems simple enough except it's for +6-19 VDC. I need to run it with 24-28VDC. It's been a very long time since my basic electronics and semi-conductors training in the Navy. What, if...
