Description: The WEKT Lucy R5 switches ditch the typical squishy, deadened feel of traditional silent linear switches by utilizing an ingenious triple-shot molded POM and TPU stem. Built with a sturdy POK top housing, an MPA bottom housing, and a snappy 16 mm single-stage spring, these 5-pin mechanical switches deliver a comfortable 55g bottom-out without any unwanted rattle. They provide smooth factory lubrication straight out of the box, making them an ideal drop-in upgrade for any custom hot swappable barebones kit. Toss them onto your PCB to build an office-friendly mechanical keyboard that actually feels crisp instead of mushy.
