This Microswitch is a more durable and reliable upgrade which you can use as a replacement for the group lever switch and the reservoir pressure plate. We have 2 version, a 10A and 16A, for the water reservoir application we suggest to request (in the comment section during check out) the 16A. For the grouphead brewing application the 10A. If no specifications are provided we will ship ether one of the two. Color of the switch body may vary NOTE: The cap will not fit on the metal tip of the switch (6mm diameter), but it will reach just fine without it. If you’re using it for the group lever, the hole in the face plate of your machine must be at least 10mm for this microswitch for fit. Fits: Amica Millennium Mondiale Relax Rituale Tea This microswitch can be used also on the Isomac Grinder Granmacinino and Macinino Professionale (both home grinders). NOTE that the metal cap will not fit on it, so it needs to be used without it.
