    I would really like a relay that behave like that!
    If it exist and the PIC can run it, that's what I want !!
    But the spec sheets aren't very descriptive in that manner...(attached Panason TN spec)

    double coils latching relays ask for 40mAh, and need 2 pins...

    About FET and other electronics switcher, i'm trying to avoid tehm because they draw some power just for operating.

    About Diodes, let's say I want to protect the PIC from the relay, I would use a 5V Zener?, or I need to add a safety margin? 4.5V?

    Lots of Amps in the coil effect of a relay?


    Thanks for all added info, i'm slowly but surely getting somewhere! 8)
