    Hi,

    I dont understand how the latching relay works. Here is the
    diagram:


    V2309-B1208-B301

    |-\ -|
    *-------* | \ | *-----*
    | | | | | | |
    | r *-----------------* r |
    s -|+ e |12 10 9 8 7 | e -|+ s
    e === s | | s === e
    t +|- e | 1 3 4 5 6 | e +|- t
    | t *-----------------* t |
    | | | | | | |
    *-------* | / | *-----*
    |-/ -|

    contacts in reset position. Both coils can
    be used as either set or reset coil.

    pins 1,12 are one coil, pins 6,7 are the other coil.

    For instance, does this mean? (below)

    pins
    time,sec 12 10,9 9,8
    --------------------------------
    1 1 closed open
    2 0 open closed
    3 1 open closed
    4 0 closed open

    pins
    time,sec 6 3,4 4,5
    --------------------------------
    1 1 closed open
    2 0 open closed
    3 1 open closed
    4 0 closed open

    can I just leave one coil open and only use the other?

    you have keep smething in mind: latching relay means
    mechanically latched. To change the relay state you have to use
    a pulse on either coil. never leave power on steady or you will not
    be able to change the state
