The invention discloses a mechanical nuclear-grade low-pressure pressure switch, belongs to the technical field of mechanical pressure switches, and solves the problem that the pressure range of an existing mechanical pressure switch needs to be adjusted in advance according to a detected pressure value. An extension seat and an air inlet pipe are fixed on the base; the induction assembly is slidably connected in the base and the extension seat, and the end of the induction assembly is connected with an induction switch through a distance increasing assembly; and the driving assembly is connected with the sensing assembly through the adjusting assembly. The driving assembly is matched with the adjusting assembly to compress or release the sensing assembly, so that the pressure value detected by the mechanical pressure switch can be periodically adjusted. By rotating the adjusting assembly, the time duration of increasing or decreasing the pressure value detected by the mechanical pressure switch can be adjust
