[Elecraft] latching relay question

[John Cooper]

If I put 5v across one of the Omron Latching relays at pins 3 and 8 out of circuit that should make it switch right?
I did but nothing happened even tried with 6V.  Currently across pins 2and3 and 8and9.  

WT5Y  Also what are pins 1 5 6 and 10 used for, their not in the schematic.  Nor do they seem to be connected internally to anything using the meter.  I just got some new and was trying em out before I put them in.
