Hello,
I'm looking to make an all in one solution to get a momentary switch working as an on-off switch. I have found the folowing schematic who does exactly what I need with a hex inverter and a relay :

I want to power this with a standard 0-12V regulated supply and put all components on a single pcb. I have made a layout but I cant figure out what is the best option (I know this is a newbee question):
- use a ground plane and connect it to the chassis.
- use the AC return and do not connect the ground.
Here is the schematic (sorry it is a bit ugly, didnt wanted to export at first) :
Here the 2 layouts :
with ground plane and ground output :
And the one without the ground connection :
I also have a question concerning the led relay (G5LE) wich is a SPDT, is it ok to ground the unused second pin as I did in the first layout? I know it would be clever to use a dpdt relay, instead of two relays but I try to use what I already have.
I know this is a lot to ask in a first post but I would really appreciate some advices.
Thanks a lot !
