Abstract
The disclosure relates to high-voltage change-over switches that are used to apply high voltage alternately to two X-ray tubes. Each of the four switch devices constituting a change-over switch includes a fixed contact element connected to an input terminal of the high voltage and a movable contact element connected to an output terminal by a curved, flexible strip, the shifting of which is obtained by a hinged arm that is actuated by an insulator sleeve surrounding the strip. The rotation of the sleeve in one direction causes contact through a hole in the wall of the sleeve while rotation in the reverse direction causes the contact elements to move away from each other and gives rise to the interposition of the insulator wall between the contact elements at a distance. The disclosed device can be applied to radiology installations.
