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.

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.
