Gear ratios and force of switch

Hey guys. For those in wednesday's pratical... does anyone have a good estimate of how much force it takes to slide a single switch?

Also, a more general question. The textbook says gear ratios typically range from 20-200. Doesn't that mean if you had one gear of, say, 1 cm diameter, you'd need a 20cm mated gear to achieve a gear ratio of 20? That seems kind of unreasonable.

You can have more than 2 gears, and I would also appreciate the force required to turn on the switch.

I tested some of them and it really depends on the model. Some are around 5N but some are around 10N.
