This kind of pressure switch was put insidereversible stainless steel motion diaphragm turns over when inducing some pressure.
This kind of pressure switch was put insidereversible stainless steel motion diaphragm turns over when inducing some pressure.
*when the electric contact (H) open and electric (L)closes simultaneously
*when the diaphragm moves.
*when the system pressure reduces,the diaphragm resets instantly,with the function of which, the electric contact disconnects from contact(L) and connects with contact(H) automatically.
