Improved contact device, characterized essentially by the fact of being constituted by a body, advantageously hexagonal, inside which is located a fixed contact body, provided with a longitudinal perforation in which a piston is housed, finished according to an extension of an insulating nature, the piston remaining on a flexible membrane, deformable due to the pressure of a fluid that penetrates through a groove made in the body and communicating with the outside, which jointly forces the displacement of the piston, in which an insulating extension is coupled to a movable contact subjected, in its housing, to the effort of a helical spring, which forces it to overcome in the fixed contact body when the effect of the fluid pressure ceases.
