D1 and D2 appear to be resistors. However, there are no assigned values to them. Which values did you use? Is this circuit correct and usable?
They're diodes. Use 1N914 or 1N4148.
Could I use single coil relays? I'm going to use Finder 3022/6 (leaving off-board R7, Q2, C5 and D1). Or can this cause some problems?
I don't think that would work- with a single coil latching relay you need to reverse the polarity of the coil to switch it. Here's a relevant thread. Short answer is that it's easier with a double coil latching relay.

Thank you, I'm not very expert in relays, I had a finder one at home and I wanted to use it but now I think I'm gonna order a few 515-587 at RS. It'll be intresting to try with the finder thus, but I should make a new circuit, if I'll do it I'll let you know. Best regards!
Hi, I found this (http://www.fennecelectronics.it/smf/index.php?action=dlattach;topic=6555.0;attach=8570;image), it's similar to this driver but it's using a single coil relay, like the one I have mentioned, I hope you'll find it useful. Best regards
Hi, thank you for the layout
I assume that the 3k3 resistor is there to limit the current to the led. If I wanted to use a superbright led, I should increase that value to, let's say, 15k, right?
thanks
I'm going to try this... I'm so tired of "clicks" and "pops".
Is there an Eagle Layout somewhere?

Thanks,

I can use it as a relay, a Takamisawa AL5WN-K?
