I am having trouble with the activation of a set-and-reset coil of a relay which is dual coil-latching.
The datasheet mentions that to set or reset the coil I need to apply the rated voltage for max. 20ms (in the coil data specifications section) and also mentions a min. 100ms pulse length to set and reset in the Notes section.
I am not sure which one to consider. I would like to know the minimum and maximum time length I can apply to the relay coil to set or reset.
I am thinking of doing it with a momentary SPDT toggle switch (I am not sure if can go with it). Do I absolutely need a control circuit to set or reset the coil? Or will an other method which is not necessarily cheap do the job? If anyone has any experience with dual coil latching please help me with this.
PS: Supply for the coil is coming from a DC supply
