HPI Roto Start button holder

The button on my HPI Roto start burned out on a flooded engine :-)

I tried replacing it with several different buttons but they all burned out also after a few starts. Picture 1 to 3....all failed.

Fujisoku APE-1F >> burned
Radiohm ST1034E >> burned

Buttons i tried vary from 24 v to 120v at 1 to 3 amp but they all fried.

So that i went for some more drastic buttons.

12mm rond 250V/1A >> lasted about 2 months
16mm round 250V/3A

So my advice is use the last one (16mm)

I made a holder that you can just clamp in the roto starter. Sand a little of the switch thread so it will go in the holder with some force so its holds. Just solder de wires.
Works great !!
