How about back to back Zener diodes ? They will clamp over a certain=20
voltage.

I've used zeners in the past when I've needed to fast switch relays but=20
never tried it with a latching relay.

Subject: [EE] back EMF suppressor for single coil latching relay

Normally with a relay, you would simply put a diode across the coils to snu=
b=20
the EMF.

With a single coil latching relay, where you swap the polarity to=20
latch/unlatch thats not going to work very well.
I've done a bit of searching and have yet to see an example of how to snub=
=20
something like this, so asking
the list if anyone has an idea?
