Abstract
The specification discloses a multiple dental handpiece control system in which lifting one handpiece out of its hanger blocks supply of power and coolants to all other handpieces. Each handpiece has an individual control unit and a blockout unit. When a handpiece is lifted from its hanger, it actuates a valve to cause a piston in its control unit to shift to a condition causing supply of power and coolant fluid to that handpiece and cutting off power to the corresponding pistons in the other control units thereby preventing supply of power and coolant fluids to the other handpiece.
