<p>A switch provides for cutting the pressure feed for distributors placed downstream of it, and for coupling the feed of these distributors to an exhaust of the switch itself, and has faces for connection with faces of the distributors, channels for circulation of exhaust fluid, members for connection with adjacent distributors, and is adapted for mounting on a conventional profiled element. The switch is particularly advantageous for ensuring the control of the feed of one or of several jacks coupled to distributors.</p> |
