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.
