Abstract
A contactor comprises, for each phase, a pair of contact devices which comprise a connection strip and at least two conductors provided with a stationary contact, and a movable contact bridge able to close the two stationary contacts or not. According to the invention, the contact device is formed from superposition of a number of pieces equal to the number of conductors, each piece comprising one of the conductors and a connection part corresponding to the connection strip but of smaller thickness. Each of the pieces can be made from folded metal. The connection parts are coupled to one another to form the connection strip by means of holes at the same time as the sets of bars are secured thereto.
