CAUTION: 1.When latching relays are installed in equipment, the latch and reset coil should not be pulsed simultaneously.  
Coil should not be pulsed with less than the nominal coil voltage and pulse width should be a minimum of three  
times the specified operate time of the relay. If these conditions are not followed, it is possible for the relay to in  
be the magnetically neutral position .

2.Switching voltage is for test purpose only and are no to be used as design criteria.  
NOTES 1).Dimensions are in millimeters.  
2).Inch equivalents are given for general information only.  
3).Relays shall have plus(+) or plus(+) and minus(-) signs placed on  
the circuit diagram as shown.
