	With ~~this switch~~ we can select which of the two sides are connected to the middle. ~~If we move the switch right then the right pin~~ is ~~connected~~ to ~~the middle. If we move the~~ switch ~~left then~~ the ~~left pin~~ is ~~connected to the middle,~~		With a button we can select which of the two sides are connected to the middle. It is similar to a [[switch]] but it only stays in the state as long as it is pressed.
