V3 low-current switch

What is the minimum requirement for this switch? i’ve got a “child” hilt that i’ll probably swap out for a v3 board so i can use deep sleep when it’s functional, but in the short term i’m thinking that maybe i can stuff a tiny little switch in there. like, really tiny. but i want to make sure i’m not going too low.

If you use the low-current wiring method, the switch will see currents in the microamp range, which is super low and any switch can handle it.
