The OMRON D2LS-21 Blue Micro Switch is a high-quality SMD switch originally designed for use in gaming mice.

Thanks to its precise actuation point and crisp tactile feedback, this switch is widely used for gaming mouse repairs and custom controller modifications.

The D2LS-21 is especially popular for Trigger Click Mods and Mouse Click Trigger Mods, where standard controller trigger mechanisms are replaced with micro switches to achieve a faster, more responsive, and mouse-like click feel. It is commonly used in modifications for R1, L1, R2, and L2 buttons.

In addition to gaming applications, the switch is suitable for a wide range of electronics and DIY projects requiring a compact and reliable micro switch.

This is an original OMRON component known for its durability and consistent performance.
