look what i found:

yes! its a small, self contained rubber dome switch! for those of us who cant stand TACT switches, but want ease of installation. it feels pretty close to the standard rubber dome in a controller.
now, i found the one above in a busted Genesis, it was the reset button.
but fear not! you need not tear apart stacks of sega systems to obtain these devices! for it is a standard ALPS switch, and i have found it!
