ABSTRACT:
A step-on actuated foot switch is disclosed preferably for use in connection with X-ray examination devices to automatically turn off motor servo drives when an operator's feet are positioned adjacent moving portions of the X-ray examination device. The switch device includes a support plate having a step-on plate suspended above the floor plate and parallel thereto with interposed switching elements which are actuated by relative movement of the two plates. The switch elements are bent spring contact devices which have fulcrum points positioned thereunder about which portions of the spring bend during relative movement of the two plates to break a contact.
