Put your nose on them. You might consider getting one with a second changeover contact.
The relay has a built-in coil that is rated at 24-Volts ACDC voltage rating.
Low voltage latching relay. A self-locking 12V single bistable relay module. You might consider getting one with a second changeover contact. You can use this to monitor the switching action and switch off the changeover pulse when the changeover is detected.
Always keep your mains wiring well away from and routed separately from the low-voltage control wiring. Generally its normal for controls like this including latching relays to run on 24V - either AC from thermostat transformers or DC from batteries if reliability is required. Lower than 24V isnt practical because you typically need to carry these control signals some distance.

A latching relay is a relay which only draws power during the brief voltage pulse required to make it change state. These are very useful in situations where energy efficiency is important but also in sitations where you need the relay to remember its state typically so that the user can press a button to close the relay and press a second button to open the relay again. While a conventional relay uses power continuously when its internal switch is to be closed relay energised a latching relay requires only a brief voltage pulse to change state.
This makes latching relays perfect for any situation in which energy saving is important for example battery powered systems where the relay needs to stay energised for extended periods of time. An electrically latched relay is a standard relay with one of its own contacts wired into its coil circuit. An external switch initially turns the relay on then it is kept on by its own contact.
An external reset switch interrupts power to the relay which turns it off. A bistable or mechanically latched relay typically has two internal coils and an internal latch mechanism. Energizing one coil sets the contacts in one position.
The field switches are to send pulses to latching relays. Which can burn out. Put your nose on them.
If theyve let the smoke out. They can be easily replaced. The actual field wiring low voltage cable – typically a seven-conductor with white as the common – is virtually immune from age.
Advantages of magnetic latching relay. It can work with single or double coils only by pulse excitation. Small size PCB type installation.
Low power consumption strong load capacity. Safe and reliable long life. Structure of magnetic latching relay.
The easiest LATCHING RELAY CIRCUIT to understand ever. Considerations when selecting a relay. When choosing a relay it is important to consider a number of specifications to ensure it is fit for purpose some factors include.
Coil voltage - the required voltage to actuate the switching mechanism. If a voltage is too high this could damage the components if it is too low then it will not actuate. Compared to a standard relay which uses 756A in a week a latching relay system will use nearly 1000 times less and this is for only 1 relay what happens if you need 23 or 4 on a larger installation clearly this low power consumption latching relay is the only sensible choice if solar or wind is used to supplement the main alternator charging system.
The coil voltage is 12VDC and the contact rating can be as low as 100ma. I need them to power leds for turnout position both on a control panel and between the ties. The OP asked about latching relays some are twin coil some use reversed polarity he did not indicate clearly what kind he wants or how he will wire them.
The GE Model RR-7 and RR-9 lighting relays are mechanical latching-type units designed for building automation systems. Each relay requires only momentary 24 volt AC switch circuit pulses to open or close line voltage circuits. All GE low voltage relays may be used to full-rated capacity for tungsten filament ballast or resistive loads.
OMRON Electronic Components has introduced new G5RL-K-EL latching type power relay that is designed for high inrush performance needed in smart building automation systems and for the control of capacitive loads. This new 16A power relay is approved to IEC60669-1 and has a high inrush current capability up to 255A which makes it ideal for demanding switching environments. The SSRL relays also convert non-latching mechanic relay outputs into latching alarm outputs or allow low power reed relay switches to control high amperage or high voltage.

This low voltage relay is used for control of lighting circuits and other electrical loads in Wattstoppers Lighting Integrator control panels. Momentary low voltage pulses from the panels control system switch the relays on or off. Mechanical latching operation results in lower power consumption.
GE Industrial Low voltage latching relay has 1-Pole and SPST contact configuration for precise operation. It supports contact rating up to 1-Amps and 24 to 29-Volt AC voltage rating. The relay has a built-in coil that is rated at 24-Volts ACDC voltage rating.
This relay supports 14 to 10-AWG solidstranded conductor for connection. It features 12-Inch knockout for comfortable mounting. In specific scenarios a particular type of switch known as a latching relay will need to be used.
As well as providing the ability to control larger currents than standard relays latching relays offer the notable benefit of having positional memory. In short once actuated they will remain in their last position without the need for any further input or current until explicitly told.
