Factory-mounted grouphead microswitches stick from time to time, making the lever activation less smooth than it should be. This Microswitch has quickly become our preferred replacement. It is a durable and reliable upgrade and can be installed both on the grouphead the the reservoir pressure plate. If you’re using for the group lever, the hole in the face plate of your machine must be at least 10mm for this microswitch for fit.
NOTE: The factory cap will not fit on the metal tip of this switch (6mm diameter), but the grouphead lever reaches it just fine without it.
