Below you can find a overview of coffee and espresso machine switches. Most of the pressure switches we sell are from the brand Sirai or Ma-ter. Most commercial espresso machines are fitted with the higher amp rated Sirai 1 to 3 phase pressure switch. Most of the Ma-ter switches are used on the domestic machines. When you are selecting a switch look for the following things
What switch was used previously on my machine;
How many phases does my espresso machine use;
What is the fitting type a 1/8 or a ¼;
What is the voltage I use for my espresso machine.
