Reviewer: from SF Bay, CA

Nice little relay for H-bridges, and very quiet. Coils can be low-end driven with 2N3904 so it's easy to interface to Arduino. Datasheet here:

Question About The Schematics

Reviewer: from VICTORIA, BC

I would like to thank the fellow from SF Bay for the link to the schematics. Very good info.
In the drawing, there appears to be a diode across the coil terminals. Wondering if someone could explain that to me.
