Turning a handle or pushing a lever
is simply 'work' as in force x distance.

But pressing it with your finger isnt either.

So when you press this 'switch' with a finger, you're not applying a
force which moves a finite distance?

Corse you are, but its the kinetic energy of the finger that
is what generates the small amount of power that powers
the chip that transmits the zigbee signal to the base.

You have show earlier you're incapable of looking up kinetic energy and
so remain ignorant of what kinetic energy is.

Or isn't "work = force x distance" any more?

Pity its the kinetic energy of the finger that is what
generates the small amount of power that powers
the chip that transmits the zigbee signal to the base.

When did that change?

It didnt, stupid.

Are you now claiming kinetic energy is the same as work? Do make up your
mind.
