Ariston DIA 20 Mffi CE Ed1&2 Microswitch.


These micro-switch assemblies have been specially designed for use with genuine Giannoni diverter valves. The Ezypart model MS04 is a triple micro-switch version, with three micro-switches mounted in a rigid black plastic housing with a snap-on cover.

The micro-switch assembly is mounted on to the diaphragm chamber of the diverter valve, retained with a spring circlip. Insulated electric cables connected to the 6.3mm (¼) Faston tags on the micro-switches convey the operating status of the diverter valve to the combi boiler control system.

When the valve is in the non-actuated position the micro-switch is also not actuated. When the valve is actuated as a result of a demand for domestic hot water, the diverter valve spindle extends out of the valve body and the push disc on the end of the spindle presses the contacts on the micro-switches. The resultant signal to the boiler control system may cause the gas valve, burner, pump and fan (if fitted) to be switched on, if not already operating.
