Improved pressure switch, essentially characterized by being a group of levers combined with a membrane that receives the pressure of the gas, and equipped with a return spring, whose levers are three in number and are arranged in succession. first of them articulated, at one end, to a fixed point, while on the other it is articulated to the second lever, conjugated, through a tractor terminal spring, with the last of these levers, which is bent and has, in one of its extremities, some contacts that cooperate with the motionless ones attached to the respective electrical conductors, of the circuit to be controlled, while at the other end it is pivoting on another fixed point, the aforementioned spring being placed so that it acts on the vertex of the lever at an angle, for the purposes of the appropriate movements due to instability of the group and there being three main stops in the device, one of them p for stopping the advance of the coupling point between first and second lever and the other two to limit the travel of these same levers in the closed circuit phase.
