Latching relay w/ momentary to power on/off MR board?

[xoliilox]

I want to use a momentary button to power on and of an MR board. Can I use a latching relay to control this?

If so, I don't exactly understand how I would wire it

This is a data sheet for one I was looking at:

If anyone knows about this, or other ways to use a momentary as a latching on/off, I'd appreciate the advice

I'm pretty sure a momentary switch won't work with an MR board.

[xoliilox]

right, I know it won't work

that's why I'm trying to find a work around

I was wondering about using a latching relay - how to set it up to respond to a momentary switch, and thus alternate between open and close each time the momentary is triggered

and I'm only trying to do this because I just obtained some mighty cool momentary switches

I am wondering if it will work as well.

You would think it would work but then again one could be wrong.

It should work. Awful big though, and you'd DEFINATELY want to wire in a kill switch cause that would constantly drain power.

you could always wire a hasbro board in in there (one without flash on startup). use the momentary to turn on the hasbro, which in turn acts as a latching switch for the MR board.

granted i have no idea about power consumption here and if you can power the MR through the hasbro.

sabercraft gods, will this work?

Xoli, you have to construct a separate circuit. Here's the info, w/diagrams.

It's still a TAD over my head, but it's possible.

Nice. Thanks! I'll try and decipher.

I think I found a solution that I can actually handle. It's called a JK flip flop and I would be running is as a T flip flop.

If you are, for some ungodly reason, interested in this, you can check out the functioning here (I don't know if it actually will be fully explanatory, but I've read so many pages that I can't tell what I used to know and what I now know):

And I think I'm going to order some of these:

I'll try and update if I can get this to work...

I asked this over at JSSCD a whiel back..and got an answer that was over my head somewhat...

the 'gist' of what I got is that is depends on the voltage..if you fall below a certain threshold..it may not work correctly..

maybe someone can copy/paste the info?

[xoliilox]

Thanks for pointing me there. I just checked out the post as JSSDC. It's referring to latching relays, and it seems they are a possibility.

At this point I think the flip flop will actually work better, I just need to figure out it's voltage requirements, and try to fully understand how the whole thing works...
