Thanks
I wanted to know this as well!

The latching relays are fairly obvious, actually.

For the dual coil ones, you apply current to one coil to open, to the
other
coil to close. The single coil ones generally have you reverse polarity
on
the coil to change state. If they are latching relays, in both cases they
won't change state with no current applied.

Anyone know a good source of surface mount latching relays DPST or

5V
to be driven by logic?

Anyone have a URL on to how to use latching relays ?. I've found
single coil and double coil examples but no info on how they function
or how to switch them.
