Abstract
A change-over switch comprises four input terminals connected in pairs to one of the two poles +HT and -HT of a high voltage generator and four output terminals connected in pairs to one of two X-ray tubes. It includes two identical half change-over switches with coupled control, each half change-over switch comprising two contact devices, each constituted by a fixed contact element and a movable contact element between which there is interposed an insulation device when the electrical contact is open. The movable contact elements and the insulation device of each half change-over switch are connected to one another to have combined movements.
