✅ - Having trouble with a DPDT switch configuration for Iron Man helmet

[rare willow]

Hi all - I've been scratching my head on this one for a couple hours now, cant figure out what I'm doing wrong, so I'm hoping someone here can spot what I'm missing.

I'm trying to replicate the bit around 19-20 mins into Franks Iron Man pt.2 video, exactly at this point: https://youtu.be/s3YNeEP8UfM?si=_n6lSBpmJby3jV70&t=1165.

I've wired everything up, with the only difference being I'm using 2 servo's and have flipped the polarity of the wires leading to and from, joined them together so that both servo's are running opposite directions as pictured.

The switches work in the sense that on one orientation the switch cuts the circuit (see video) but the issue is that both switches are cutting the circuit via the same direction, whereas I want them to cut power via opposite rotations like shown in franks vid, as I want to use one to stop the circuit when mask is fully closed, and the other to stop when mask is fully open.

Any ideas?

Nvm I figured it out - apparently aligning the Servo's on the same side i.e. top right and bottom right makes it work.. does anyone have an explanation as to why that would be, for lessons learned? It doesn't make sense to me :/
