I built something similar a million years ago, and as I recall it took 5 or 6 relays to provide the latch and lock-out features. A micro controller would have been easier. |
I wish we had been able to use phones, but in those days they had to be connected to Ma Bell and didn't run Apps ;-)

Very nice boxes, Doug!!! |
I like them a lot.

I have a computer stamp from Paralax , but not much time spent with them . |
I was trying to figure out how to go old school with relays . I found a good YouTube video on latching a relay also , but I couldn't get it threw my head how to make it so the first one latching would effectively lock out the others without a whole bunch of other relays and wiring .
I know I'm missing something simple here

A couple of things that I would check: |
Test the voltage across the switches. With the switch not pressed it should be the supply voltage (5 volts?), pressed it should be 0.
Are your switches NO (Normally open)?

|old coasty||Doug, It's amazing how things go adrift when you go to sea on a regular basis.|

Doug the boxes look great and problem may be the controller program like you mentioned. I know a lot of things work great until they update the operating system and everything just stops working. Maybe it will be as simple as finding an update to the controller. |
Good luck figuring out how to get them working, sounds like you have some help on the way.

Glad you understand, please post the outcome of this dilemma. |
