Im trying to build a flat, battery powered PCB assembly that fits into a small gap of approx. 2mm. I have found the CR2012 coin cell with a thickness of 1.2mm, which would be a good fit in terms of size and energy.

My problem is that I have no clue how to connect this battery with my electronics PCB. I searched for battery holders all over the web, but all I found was holders for CR2032 (3.2mm thick) batteries that also would work for CR2012 coin cells (e.g. this one).

What I seek for is either a proposal for a battery holder for CR2012 with approx. <1.5mm thickness or some general ideas how to connect such a battery (reliably) with a PCB electronic circuit without exceeding 2mm thickness constraint. (The PCB can be as thin as 0.5mm).

One possible battery holder I was seeking for is this one. It has a thickness of 1.7mm above PCB, which slightly misses my constraint of <1.5mm. (Maybe there are better proposals?)
