Will these relays work in the Softie?
« on: July 21, 2020, 11:54:41 AM »
I happen to have a couple of these that came in a mystery box assortment from Electronics Goldmine:

They appear to be non-latching ("single-side stable" is what the datasheet says) 4.5V coils with the same contact configuration as the one in the Softie build doc.  Is there anything else I should be aware of, or would these work just fine with the Softie?

Datasheet:

Itís a relay I believe. See Madbeanís softie.

It's definitely a relay.  My question is whether it is an ok substitute for the one spec'd for the Softie.  It has the same contact configuration and coil voltage.  I just want to make sure there aren't other datasheet numbers I need to pay attention to.

That looks fine to me.  I was surprised that it was the non-latching type, but I checked and that's right.  I've yet to build a Softie but I've used this relay type in other soft touch builds, 4.5-5.0V 1-2A.  I've used the ones from Tayda:

Thank you for your input (I forgot to say that before  :-[). 
I have now soldered up a Softie with one of my relays, and it does seem to work.  It passes the LED test, and the relay sounds like it is properly clicking on and off.

The relay also clicks on then off once quickly when power is first applied.  I'm guessing (hoping) this is normal.
