FOOT PEDAL CONTROLLER FOR DENTAL SCALER

摘要

A method for controlling a dental instrument includes a foot pedal responsive to commands from a user. An operating mode is selectable between normal and boost cycle. A conventional mode is selectable by pressing and holding the foot pedal to a first level to operate in normal mode. The foot pedal operates in a boost mode when the pedal advances to a second level. Maintained mode is selectable by tapping the foot pedal to change modes between idle, normal and boost mode. Each mode is switched by tapping the foot pedal. The pedal switches between the second process and the first process by pressing and holding the foot pedal at the desired level corresponding to normal or boost mode. The pedal switches from the first process to the second process by tapping the foot pedal at the level corresponding to normal or boost.
