Interruptor mecánico Ducky TTC Heart DSK110-LPA1 lineal 42 g 3-Pin

Ducky TTC Heart DSK110-LPA1 Linear 42g 3-pin is a mechanical keyboard switch engineered for a light, smooth linear keypress. With a 42-gram actuation force and a three-pin housing, this switch is intended for conventional PCB mounting or compatible hot-swap sockets. It delivers consistent travel and a predictable feel across repeated presses, making it suitable for both daily typing and fast-paced gaming where low resistance and uninterrupted motion are preferred.

Advantages

The switch offers a low actuation force of 42g for reduced finger fatigue during extended sessions and a linear travel profile that eliminates tactile bumps or audible clicks. Its three-pin design ensures broad compatibility with most mechanical keyboard PCBs and plates, while the internal TTC Heart mechanism provides stable, consistent actuation characteristics. The construction supports reliable performance over many keystrokes and helps maintain uniform response across the keyboard.

Suitable for (tasks / use cases)

• Daily typing where a light, smooth keypress is preferred
• Competitive and casual gaming requiring fast actuation and repeatable strokes
• Custom keyboard builds with 3-pin PCB or hot-swap sockets
• Users seeking a quieter linear alternative to tactile or clicky switches

Key specifications

• Switch type: linear
• Actuation force: 42 g
• Pin configuration: 3-pin housing
• Compatibility: standard mechanical keyboard PCBs and compatible hot-swap sockets
• Intended use: typing and gaming

How to use

Install the Ducky TTC Heart linear switches into a compatible mechanical keyboard PCB or hot-swap socket following the keyboard manufacturer’s installation instructions. For solder-mount keyboards, insert the three-pin housing through the plate and PCB, then solder each switch pin securely. For hot-swap keyboards, align the switch pins with the socket and press firmly until it seats fully. After installation, test each key for smooth travel and consistent actuation; adjust keycaps or stabilizers as needed for optimal fit and feel.

Recommendations

For longer switch life and consistent performance, avoid exposing the switches to moisture and excessive dust. If you disassemble or mod the switches, use proper tools and anti-static precautions. Lubrication or spring swapping can be considered by experienced users to further refine the feel, but follow safe, manufacturer-aligned practices to avoid voiding keyboard warranties.
