Abstract
A surgical footpedal includes a treadle size for receiving a user's foot and adapted for enabling depression thereof in order to activate signals for control of associated surgical apparatus. A vibrator is disposed on the treadle for vibrating the treadle at selected treadle depressions to provide sensory warning to the user that further treadle depression will cause a given event to occur. A bracket is provided for attaching the vibrator to the treadle for causing resonant vibration of the treadle and the vibrate.
