Schematic
— Energize relays only in the polarities shown —
1. Single side stable
Same operation as conventional magnetic relays.
Contacts will transfer only when coil is energized under indicated polarity.
2C
4C
deenergized coil
energized coil
2. 2 coil latching
Contacts will transfer only when coil is energized under indicated polarity.
Once transferred, contacts remain in that position even with power off until opposite coil is energized at indicated polarity.

Diagrams show the "set" position when
terminals 4 (–) and 5 (+) are energized.
When the coil current is switched off,
these contacts remain in "make" position.
Energize terminals 3 (–) and 6 (+) to
transfer the contacts.
Diagrams show the "reset" position when
terminals 3 (–) and 6 (+) are energized.
Energize terminals 4 (–) and 5 (+) to
transfer the contacts.
