Operation
The Putikeeg CW Morse Key Replacement part is designed for intuitive operation with your compatible Morse code keyer.

Using the Left/Right Hand Switch:
The CW Key button features an internal switch that allows you to configure the paddle's behavior. This switch enables you to alternate between two common configurations:
- Left Dit, Right Dah: In this mode, pressing the left paddle generates a 'Dit' (short signal), and pressing the right paddle generates a 'Dah' (long signal).
- Right Dit, Left Dah: In this mode, pressing the right paddle generates a 'Dit', and pressing the left paddle generates a 'Dah'.
Adjust this setting according to your preference and operating style. The switch is located internally and can be set during installation or by carefully accessing the internal components.
