XK-3 Foot Pedal


  • Great for transcription playback control
  • Alleviates RSI issues (replaces finger actions)
  • USB connection

Holding the center pedal down keeps the mouse button active to allow for drag and drop operations. Clicking with a foot alleviates RSI issues if the operator experiences pain performing mouse click operations with the hand.

Resting a foot on the center pedal activates a command. Perfect for dictation playback, microphone activation, or media playback. The outside pedals hinged in the rear provide additional functions easily reached to the left or right of the main pedal.

We also offer a Media Player Foot Pedal with all the features of this pedal but pre-programmed with Play/Pause, Previous, and Next multi-media commands for instant plug and play operation.

For functions where momentary activation serves the task (mouse clicking for example), we recommend our XK-3 Front Hinged Pedal.
