Pressure switches play a crucial role in regulating internal pressure within boilers and closed systems. They can be associated with water, air, or gas, and their function is to control the flow of specific materials based on pressure variables.

This particular part is featured in 13 different boilers within the Saunier Duval range, including models such as Saunier Duval ISOFAST F 28 E, THEMACLASSIC F 24 E, THEMACLASSIC PLUS, THEMACLASSIC F 30 E, and others.
