Current
600 mA (typical 700 mA; 500 mA
quiescent + 200 mA for switching)
Quiescent Current Requirement
Most latching switches require some small amount of quiescent current to remain in their position.
This current can range from 1 to 2 mA to 50 mA to 40 mA. Be sure to calculate your quiescent cur-
rent needs using the 5989-2272EN Configuration Guide.
Example:
12 87106C nominal quiescent current: 12 x 30 mA = 360 mA
Plus 6 N1810TL nominal quiescent current: 6 x 1.5 mA = 9 mA
Total nominal quiescent current = 369 mA
