Hi,
This could wll be the place to answer (almost) all of my problems...
I have a problem that im sure could be solved by some electronics genius out there. Basically i need a circuit that has 6 illuminated momentary pushbuttons as inputs, each one with 12v illumination. The outputs need to be 6 x 12v relays, one for each button.
OK so far... the snag is that the outputs need to be momantary (about 1 second) but the illumination needs to latch constantly on the selected button until another one is pressed.
The circuit is to extend the front panel of a seamless AV swithcher to anti vandal illuminated pushbuttons. I can interface the relays into the switcher but I would like the anti vandal buttons to be illuminated too, hence my problem.
I have found a circuit where the output relays latch until another button is selected however this has adverse effects on the reliability of the switching.
I can use Eagle to turn schematics into boards, im just not too bright when it comes to design!
I hope that someone out there can shead some light onto this for me (no pun intended)
Cheers,
Joel.
