Re: Latching Relays -- suggestions on make/model
When I say latching, I mean it in the context of "A latching relay hastoggle quoted messageShow quoted text
two relaxed states (bistable)." ( http://en.wikipedia.org/wiki/Relay )
The idea would be to apply voltage one way throught coil to get
switched to one state. Then voltage need not be sustained to stay in
Then to switch the voltage applied in the other direction through the
coil and the switch stays in this new state with again the voltage
This way you just bump it once with current to switch to either state
without sustaining current to a coil.
My case is switching double throw ON-ON' states.
I have a circuit that I would prefer to not have the battery power
sustained to the relay coil, hence my interest.
Most relays I see are Normally Open but what I'm interested in is
bi-stable On or On'
I have not figured out how I will use it in the bitx20 just yet, to be
honest it's for another project.
Thanks for your input Arv. I suspect the Wikipedia entry might be
more clear as to whether all latching relays are bistable or if they
are just a specific type of latching.
