Touch CW Key is a compact, touch-sensitive Iambic Morse key powered by a single CR2032 coin cell battery.

It eliminates all mechanical parts, offering a smooth and silent keying experience ideal for portable CW (Morse code) operators and QRP enthusiasts.

This modern approach to a traditional Morse paddle uses capacitive touch sensing to detect left and right paddle inputs.

With ultra-low power consumption and lightweight design, it’s perfect for field operations, minimalist stations, or embedded keyer circuits.

Key Features:

• Touch-based Iambic Key – no moving parts, long lifespan
• Power: CR2032 lithium coin cell
• Ultra Low Power operation for extended use
• Logic-level output, compatible with CW keyers and microcontrollers
• Compact and durable PCB design
• Ideal for QRP, portable, or embedded CW setups

This open-source project is designed and shared by Uğur Altınsoy for CW operators who appreciate innovation, portability, and reliability in

Morse communication.
