Claims

[Scope of utility model registration request]

a switch body having a passage through which pressure fluid passes; a diaphragm sealed in the switch body; a stopper that contacts the diaphragm and is movable together with the diaphragm within the switch body; a movable receptacle provided in the switch body and having a hole in the center on the side to which the switch is operated; a first reversing plate supported by the receptacle and a stopper; A movable guide provided in the switch body and having a guide opening in the center, a second reversing plate supported by the guide and the receiver and having a hole in the center, and supported by the guide and the inner peripheral wall of the switch body. a third reversing plate having a hole in the center; and a third reversing plate provided facing each other and perpendicular to the switch body, with one end thereof being exposed inside the switch body and each other end being exposed outside the switch body. two pairs of terminals, a switch lever attached to one of each terminal, each having a movable contact facing the fixed contact of the other terminal, and having elasticity to keep the contact open at all times; a cylindrical first actuating rod that is provided between the second reversing plate and loosely passing through the opening of the guide; passing through the one switch lever, the first actuating rod, the second reversing plate, and the receiver; A pressure switch comprising a second actuating rod provided between the first reversing plate and the other switch lever.
