Koala switches are 5pin tactile switches with 62g springs.
They have been treated with Tribosys 3203 grease on most surfaces, avoiding the legs and pads for a slippery smooth feel without affecting tactility. Springs are oiled with Krytox 105 oil to minimise spring crunch and ping. Deskey white films are placed between the top and bottom housings, reducing wobble and errant sounds.
Comes in a bag of 90.
