Outemu Butterfly Silent Linear Switches

The Outemu Butterfly Silent Linear is a mechanical keyboard switch designed for users seeking a quiet and smooth typing experience. It incorporates advanced silencing technology and high-quality materials to deliver reliable performance for both gaming and professional use.

Silent Linear Performance

This switch features a linear actuation profile, providing a consistent and smooth keystroke without tactile bumps or audible clicks. The integration of TPU soft plastic on the stem railings significantly reduces noise during both the upstroke and downstroke, making it ideal for environments where silence is essential.

• Linear switch type for smooth keypresses
• TPU soft plastic silencing mechanism on stem railings
• Quiet operation suitable for shared spaces

Construction and Materials

Durability and stability are ensured through the use of hardened polycarbonate for both the top and bottom housings. The stem is crafted from a combination of POM and TPU soft plastic, further contributing to the silent operation and longevity of the switch.

• Top Housing: Hardened polycarbonate
• Bottom Housing: Hardened polycarbonate
• Stem: POM with TPU soft plastic
• Spring: 20mm, single
