The on/off switch is not available to retail end users from Mr. Coffee. I checked ereplacementparts.com (which has a good supply of parts for almost anything), and they recommend contacting an authorized Mr. Coffee repair place. (http://www.ereplacementparts.com/coffee-ecm20-espresso-cappuccino-parts-c-116130_116133_116388.html) So if you wanted to do it yourself, you'd have to find an aftermarket switch to use, rather than the OEM.
