Teledyne makes a 'non volitale' relay. its

Lots of manufacturers make latching relays (or at least used to. I
haven't had need to use one in over 10 years). We used to use them
for power switching in most of our designs. At one time we had to
switch away from teledyne relays because they could end up in an
indeterminate and worse uncommandable state if exposed random
vibration levels normally associated with the launch vehicles we were
using. I believe they eventually fixed that issue, but it caused us a
lot of problems in trying to find a replacement in a similar form
factor.
"latching relays" only brings up 53000 hits on google, so I assume
they are still fairly common.
