A light switch is a bit like a fulcrum, but it's not designed to transmit much physical work -- rather, it's designed to make or break an electrical contact when the switch is flipped.
I will not list 20 simple machines around the house. Do your own homework! Yeesh.... how do you suppose you will benefit from your schooling if you can't do the homework?

The simple machines include the inclined plane, the wheel and the lever. You can probably find many examples of those in your home. Other machines that are more complicated are made of combinations of simple machines. For example, the screw is an incline plane wrapped around in a cylindrical form. The pulley is basically a wheel. A wheelbarrow is a combination of a lever AND a wheel.

A light switch is a lever, so yes. Hmm...can't give you twenty, but here's a few. Knife (wedge), scissors (wedge and lever), your curtains have pulleys, car (wheel and axel), same with a pizza cutter, automated garage door (screw), a fan (inclined plane).
You can get the rest on your own, lazy. ;)
