Switchable Magnets.

I thought that even the cavemen understood gearing ratio.  Apparently some Neanderthals have survived.

@ACG,

A lever would help too.

Gearing does not amplify energy, it wastes it as heat due to friction.  That would simply add another loss to the system.

Doubling the magnetic force in an Electro-Magnet requires raising the input by a factor of two. Doubling the holding force of a "Magnet Switch" is practically free from the "Flux De-Coupler" advantage.

A practical approach towards motorizing the" Magnetic Holding Force" of these kinds of switches has been slow developing and is currently a "Horse and Buggy" era mechanism.

Here's a high pressure low stroke neumatic reciprocating pump. The pump rod would hook directly to the "Rocker Arm".

Here's another email response I got about the "Noga 0039" with 283 pounds of holding force at "Amazon":

The question was: Does the switch require more force with increased holding force?

Answer from Kevin:

"No the switch turns on off the same as the smaller size"

NOGA Magnetic Holder Bed - Model: DG0039

Another answer to the same question from Selecio:

"All the same".
