You can ignore this ... but I was genuinely about to post about something along these line ... I was wanting to look into using optical or hall-effect switches ... I can only imagine the performance and durability benefits there.
Don't buy them as they are absolutely crap quality.
I usually buy the OMRON (Japanese) which are superb quality and last a long time.
They don't come with the lever but you can open them and transfer the lever .
These are the ones I use as replacements. Check the length of the lever. Longer ones can be trimmed down.
Also check the sprung force, usually in newtons or gf and get the same as the others, or replace all four to be lighter or heavier.
