Kailh Speed Bronze and Kailh Box White are clicky switches. Kailh Speed Bronze switches have a shorter pre-travel distance and somewhat better latency performance, making them better suited for fast-paced gaming. On the other hand, the Kailh switches are more stable-feeling due to their perimetered stem design. They also have a click bar design, which means they make a clicking noise on both the downstroke and upstroke.
