Soft start & Soft Switch circuit: can anybody help? - Page 10

Hi,
just noticed that the K2 unused poles are close to the ground protect track. What is the gap?
Q what gap do you need, 1.6mm?

There is a fused mains switch that disconnects both lines.

but maybe it would be better to disconnect both lines using the relais.

the unused pads of the relais are never high, so the gap is not that important i think.. it is 1.5 mm by the way..

thanks for Your feedback

Hi,
K2 unused pins go high when K1 is energised and K2 is low.

ah, good point, didn't noticed that..
I changed the layout to accomodate other relay types.
all gaps between the 220V lines are 2mm or more

thanks

Can you move R12 above R13 and get rid of the jumper?

Good idea, thanks.

I've been staring at the thing for a long time to eliminate the jumper, but didn't see it..

I also did some more fine tuning
here's the latest version
