Hello! This is Will and I'm going to teach you how to turn a button into a lever! Many people like to use a circuit called an R S Nor Latch to do this, but I use a different method. It is called a Toggle Flip-Flop. The main difference between a Toggle Flip-Flop and an R S Nor Latch is that in an R S Nor Latch, there is a button to turn on the signal but there also has to be a seperate reset button. In a Toggle Flip-Flop, the button to turn on the signal and the reset button are the same button!

You will need:

-1+ redstone dust
-1 redstone block
-2 sticky pistons
-1 redstone repeater
-3 blocks of choice
-And of course, 1 button

Here's how to do it:

First, place your blocks. Let's say that an O represents a block. Place your block in this formation: 
   O
O   O
Under the highest block, place a sticky piston facing upwards. Then, on top of the block farthest to the left, place a redstone dust on top of it. Also place your button on the block farthest to the left. Next, place a redstone repeater on top of the block farthest to the right. Then, you must place a sticky piston one block to the right of the repeater facing to the right --->. The sticky piston should be in mid-air. Next, place the redstone block one block to the right of the last sticky piston you placed. Finally, you just go one block to the right of the redstone block and on the ground there, you can place redstone however you like. Just make sure that one of the redstone dust is one block to the right and down of the redstone block. Thanks for reading!
