There’s optical and magnetic/hall effect switches, but those are usually still a linear spring force.

I thought there were some with programmable actuation force profiles, but I can’t find it with a quick search.

I chose mander.xyz and feddit.nl partially because neither require an email address. I haven’t really kept track of who all they have and have not defederated from. I think both don’t defederate much. I use the block feature in Connect liberally to remove the communities I don’t care to see, like the tankies.

I set up multiple profiles on different instances as there were quite a few downtime events when I started. Now things are a little more stable and I only use two. I wonder how much of that decline is from redundant profiles going dark without actually losing the user.

Blue switches are not a good choice for office use if the user shares a space with others or has video meetings. I find typing on a red switch to be just as fast and comfortable as on a blue switch. Brown is a good in-between.

Check out the Kechron C2 or Logitech G413.

I recommend getting a red switch from a retailer you know has good returns and see if she likes it as much as yours. Or maybe go to a best buy together and have her try out a couple different switches.

Ironically, John Deere used to be a good example of supporting machines for a long time. I was able to get gaskets for a 33 year old tractor from them back in the early 2000’s.
