ABSTRACT:
A pressure responsive switch in which a bellows abuts against a leaf spring at substantially the same point where a switch actuating rod abuts against the leaf spring. Within the casing, the bellows is attached to a first inner end and a switch section is provided at a second inner section. The actuating rod extends in a direction of the bellows expansion between said bellows and the switch section. A first end of the rod is positioned opposite the bellows. The leaf spring is interposed therebetween to counteract the bellows expansion and exert balanced force to the actuating rod.
