Rockboard S-Connector nickel

Ive recently been building a pedal board for the function band shows I do. I own couple of Boss Pedals and have been trying to find a way to take up as little space as possible on my board. Usually this style of connector wouldn't be possible, but as I am using the same company pedals, the jack sockets line up perfectly... or so I thought.
I plugged two pedals in, and they seemed to work perfectly. So I wired everything up and took them on a gig. Cut a long story short, everytime I hit either of the pedals, there was a weird crackling sound. So after the gig the next morning I ran a few tests. Basically even though the Boss pedals appear to have the jack socket in exactly the same place, they're ever so slightly different. So whenever I pushed on one pedal, It would act as though I was pressing down on the jack socket on the other, therefore creating the noise.
Its a shame as these connectors are cheap, and small. As an alternative, I recommend "Rockboard" or 'EBS" patch leads. Thomann sell both. No noise, and equally as compact.

I bought this to connect some guitar pedals and for what this connetctor is, it has decent build quality and doesn't create unnecessary noise. You really should look into connectors like these before buying them, though.

In most cases these are unsuitable to connect pedals from different brands as they place the jacks at different heights. Even on pedals from the same brand, due to imperfections or slight differences in manufacturing, the jacks may be at slightly different heights, and you can't really connect more than 3-4 pedals without noticing some obvious curvature. This puts strain on the jacks and could potentially damage them, especially when you press down on them.
You don't save THAT much space either, especially if you have flat patch cables, in which case, they take up about the same space. Overall, you should probably look into getting some patch cables if you're looking to use them on a pedalboard.
