Mazzer Mechanical Timer Switch - Doser GrindersThis mechanical balance-wheel timer switch is used across a surprising range of doser grinders - it's the same part sold under Mazzer, Ascaso, Astoria CMA, and Fiorenzato numbering.SPECIFICATIONS Bipolar (single phase), 16A 250V, suitable for 110/115V Manually set ~50 second cycle, mechanical balance-wheel movement Max ambient temperature: 125°C 3.5 x 3.5mm square pin terminals COMPATIBILITY Fits: Fiorenzato MC F5 and F6, Mazzer M100, Mini, Lux, Super Jolly and Major Replaces: Mazzer S000TIA02, Ascaso MAZ..5, Astoria CMA 28162, Fiorenzato M.C. 001.004.028, Fiorenzato 600000029, Ricambi Gardosi MA008 INSTALLATIONA straightforward electrical swap for anyone comfortable working with 250V wiring. Note this part is non-returnable once installed - see our Return Policy.PRO TIPSNever force this switch back to the "off" position by hand - the balance-wheel movement resets itself when the timed cycle completes, and forcing it will strip the internal mechanism and require full replacement. If your grinder's dose timer has become erratic or won't complete a full cycle, that's the classic sign this switch has worn out, not the motor.
