Is it possible to fix a mazzer grinder switch on my own?

So this grinder cannot turn off. The only way I can turn it off conveniently is if I install a single port switch to turn it off.

Are the parts to replace the timer switch that I can buy and will that fix the problem?

So basically, I plug in the machine, the timer won’t turn it off. I have to unplug it. And adding a single port can still be a bit time consuming because i need to bend down to the outlet every time.
