The scenario
User needs a schematic for a two-coil latching relay that consumes power only during state change.
What is in this drawing
Read the decisions behind it.
01
Use two separate coils for set and reset operations
02
Momentary push buttons allow brief energization of each coil
03
Load is connected via a normally-open contact that mechanically latches after the set pulse
When designing control circuits that require a relay to maintain state without continuous coil power, such as in battery-powered devices or industrial controls.
