I am interested in knowing whether it would be possible to latch/unlatch a binary event using another binary event and one or two relays.

 

Google: pulse on pulse off with relays

 

What is the nature of this "binary event" signal?

 

Could you please post a timing diagram for easier understanding?

Regards,

Nandu.

Latching a relay circuit is entirely possible. But what you are actually seeking to accomplish is very unclear.

 

Relay Latch/unlatch with single P.B. i.e. Flip-Flop.
Max.
