Intellivision reset switch

Can anyone who's been inside an Intellivision confirm that there's supposed
to be a little foam disc beneath the reset switch plate?
I picked a system with a box of cartridges up earlier, half expecting the
machine to be dead (I was figuring it was going to be a blob of
easily-dead-after-so-many-years custom logic inside, but it's more like a
"real computer" in nature). It *was* dead, but the [initial, at least]
issue seems to be that the reset switch consists of a metal plate which is
supposed to make contact with the PCB when pressed - and presumably is held
away from the PCB by something when at rest. Except that there's no
"something" in this machine - with the machine the right way up, the plate
is free to contact the PCB, holding it in permanent reset.
I'm guessing it was a blob of foam, which has deteriorated, but maybe it
was a metal spring, or a piece of u-shaped plastic etc.
