This batch, and all future batches, of Alpacas have what is commonly referred to as “V2” housings.
Alpacas are smooth linear switches with gold plated 62g springs (bottom out). Colors are based on the SA Bliss colorway brought to us by Minterly.
Top housing is polycarbonate. Bottom housing is nylon. Stem is POM. These switches are PCB mount (5-pin). Lightly lubed with a thin oil.
