Pressure switch XP200A 0.5-1.5 bar 1/4"

The Ma-Ter XP 200A pressure switch. Is more uncommon model in the Ma-ter espresso machine switch assortment. This type of double pressure switch is used on La Carimali espresso machines.

The thread used a ¼” BSP-G. The pressure reach is 0,5-1.5bar. It is pre-set at 1,4 bar. The switches are both rated for 16A at 125/250V.

The Ma-ter XP pressure switches are adjustable. But don’t try to adjust them constantly, the mechanism inside the pressure switch isn’t made for that.

The principle of a spring actuated pressure switch is that when the boiler pressure raises, a membrane goes up and when it reaches the set pressure the contacts will disconnect. This results that there goes no power to the heating element anymore. When the pressure in the boiler lowers the contacts will connect again and the heating procedure starts over again.
