OA (Original Aspiration) switches are JWK linear switches with a 67g spring in a brilliant blue colour. They have a polycarbonate top housing, UHMWPE bottom housing, POM (polyoxymethylene) stem, and 5 pins. These are from the first batch of extras and not the group buy stock.
They have been treated with Krytox 205g0 grease on all surfaces for a buttery smooth feel and modulated upstroke and keypress sound. Springs are oiled with Krytox 105 oil to minimise spring crunch and ping. TX clear films are placed between the top and bottom housings, reducing wobble and errant sounds.
Comes in a tub of 90.
