Which can be considered an advantage or a disadvantage, depending on the personal taste, surely the activation at the bottom came first, on the mechanical typewriters.
The Topre uses a spring and a capacitive contact, and the domes are used only for tactile feeling, without the need to bottom out. So they feel better and last much longer, both in feel and functionality.
Surely a switchless keyboard like a topre will never have a broken switch, but the lasting time depends here like on the other RD boards, on the plastic quality, on the tolerances, and on the rubber quality and design.
Now while we all know that zillions of Olivetti boards can feel like new after 25 years, almost no one has tested a Topre board for so long time, the Olivetti durability is a fact, the Topre durability is a reasonable hope.
The idea here was solely to lower production costs at the expense of quality, in order to be more competitive in the PC price wars of the time.
The competing Model Ms were built to be more expensive ?
Olivetti and IBM did exactly the same thing, they lowered the production costs using their unmatchable knowledge, the only difference was that the Olivetti HW was also nice looking.
So I doubt Olivetti somehow found the holy grail of a keyboard made to be cheap and with the same limitations as other rubber domes, but nevertheless beating that and providing a superior feel.
Surely they managed to build keyboards with a feeling on par, if not better with model Ms, making them also silent maybe not the holy grail but really close.
