Abstract: A modular differential spring and contact assembly is adapted for mounting on a pressure sensing module in selected positions providing optimum sensitivity for different spring rates of the pressure sensing components. Independent adjustment means are provided for range spring force, differential spring force, differential pick-up, and sensitivity so that the pressure switch assembly is operative in a wide variety of pressure ranges with different pressure sensing means, range springs and contact means.
