Subject: Simple (and effective) Rocky Front Switch Modification
 

Hello everyone

Lately I've been trawling through the forums trying to find an up to date solution to avoid having to hold my finger on Rocky's front switch while I grind beans for my shots.

I discovered a few different solutions - some involved using tin foil, some involved cutting wires, some involved making new wires, some involved removing switches entirely and some involved duplicating switches.  I found one that I think is the simplest and quickest to use.  I simply removed the spring from inside the front rocker switch so that the switch behaves exactly like the side power switch to start and stop grinding - no continual pressure required.

You will need to unplug your Rocky first.
Then lie it on its side or back and remove the three screws from Rocky's base.  The stainless steel base will slide away from the rest of the grinder.
Locate the black rocker switch and unplug the two wires from it (remembering which wire goes to which terminal on the switch).
Then remove the switch from Rocky's body by pressing down the tabs with a flat, small screwdriver (or something similar).
Once the whole switch is out, remove the rocking part of the switch by applying pressure to the small circular plug on each side of the switch (there are two of these in total).
You should now be able to access the inside of the switch body.  Remove the spring on one side of the switch (leave the spring from the middle of the switch in its place).
Reassemble the switch with the spring removed, and then reinsert the whole switch back into Rocky's housing.  
Reattach the wires to the switch terminals and put the base back onto Rocky.
Now plug Rocky in, turn the white side switch on, and now you have a proper on/off switch on the front and can grind without holding the switch in!

Happy grinding!

PS: Another easy solution (although it will cost you USD13 or so) is to buy a replacement white switch (like the one on the side of Rocky) and simply swap out the black switch on the front with the new white one.  For those of us who don't live in the US and may not be able to get a replacement switch, the above mod is just as good.
