blocked by #960 (selection of switch)
We will for now model with this one: https://www.digikey.com/en/products/detail/e-switch/R1966CBLKBLKGF/1805114 as was tentatively decided in #960 Does it need to be recessed to prevent accidental flipping?
Turns out the barrier type is this one: https://www.digikey.com/en/products/detail/nkk-switches/JWM11BA1A-A/1058358
But for now, we have already purchased these, so let's model for that and we can adapt it later: https://www.digikey.com/en/products/detail/nkk-switches/JWMW11RA1A/671485
