No, a latched relay changes state with start of each pulse and don't care if you continue to power or cut power. Then you would need to read the state of each relay switch (which is attached to a pull-up resistor on one end and ground on the other. You would need to energize the switched circuit and read the status of each latch relay before you apply power to the coil because the coil will trigger to the next state when you re-energize it (unless you have a way to keep power on part of your circuit).
I don't understand your answer.
I've been doing research and questions for some time to understand something about bistables. that's why I asked the question here:
Hello. I need a bistable relay expert to ask him a few questions. can you tell me a person? .

there are apparently three types:
1 coil 2 terminals, 2 coils 3 terminals, 2 coils 4 terminals. then there is a fourth type, the polarized ones that make use of a permanent magnet.
then there is the step-by-step and the REED one.
until yesterday I was convinced that all types, excluding that step by step, were polarized.
instead today I read this link:
**broken link removed**
on page 2 under the title Remanence relays. therefore it seems that the core remains magnetized even when the power supply is removed. I don't know if it works the same for REEDs.
therefore, when the power supply returns, the HALL sensor reads the status of the core. however, if the magnetic flux does not change direction, the HALL sensor does not change state and is therefore unusable.
what type are you referring to?
