Latched relay question
 
Quick question:

This is a relay pulled from a thread of someone who used a latching relay to turn a ground wire into a switched ground wire.

How would I wire that so that it has a constant ground, but the result is a switched positive?

Should be a simple answer but I'd rather not guess!

Many thanks.

56 will be your output.
56a 56b will be positive an negative. You can flip them depends on the polarity you want to use for the trigger (S).
If uour trigger is negative, then 56b will be positive.

Oh, that's interesting - I already had an answer from boxa.net and was this:

Is that not right?

it should work if you only need to turn positive pulse to constant.
i guess i misunderstood your original post.

BTW, the diagram on the relay is a bit confusing, and not accurate.
in reality legs 56a and 56b are isolated from each other.

go by this one.
