I have a rotary switch with 20 x 2 pins in a rectangular form, and I need to connect almost all pins, so I thought of buying a stripboard for that.

The problem is that the spacing between the pins is about 1.9mm — I can't find stripboards with this pitch on the internet... (The distance from pin 1 to pin 20 is 38.5mm, so 38.5mm divided by 20 is 1.925mm - so around 1.9mm from pin to pin.)

Is there another way to connect all those pins? I could, of course, make my own PCB board, but I don't have a that good of drilling machine for those small holes.

What would you suggest?

    \$\begingroup\$ Ordering small-quantity PCBs costs < 10€. Go for that. e.g.: oshpark.com, aisler.net. With a bit of luck, someone else already made a footprint for any of the nicer PCB EDA tools (if you don't know one yet, I'd recommend KiCAD, it's free as in beer (which is awesome) and as in speech (also awesome)). \$\endgroup\$ – Marcus Müller Feb 26 at 11:10
