Overview

SP-Star RedBlue Linear is a two-tone switch, pairing a red stem with a translucent blue polycarbonate housing that gives it a distinct look among boutique linears. Both the top and bottom housings are polycarbonate and the stem is POM, a combination chosen for a clean, uninterrupted downstroke without a tactile bump.

Retailers generally position it as a balanced choice for both gaming and typing, and several offer optional lubing or filming add-ons alongside the stock switch.
