You place an observer by hovering over the block you want it to “observe” and placing it against that block. Doing this sets it up so that the observer face (input) is pointing at the chosen block, and the output side comes out the opposite end.

In order for you to understand how to use an observer, you need to first understand how it works. There are two main parts to the observer: the face and the red signal button on the back.

Observers are blocks that detect a change in the block state of the space in front of them. This makes them useful for farms and other redstone contraptions. However, when using them with pistons, observers are prone to creating pulse circuits if not placed carefully. However, stabilizers can be used to ‘cut’ the circuit after one pulse, using the locking mechanic of redstone repeaters.

The face of the observer should always point at the block you right-click on to place it. So all you should need to do is just place it against the thing you want it to “observe” directly. Your position isn’t as important.

You can place them on the floor either pointing east-west or north-south, but you can’t point them so that one east-west floor switch has east as the off position and another east-west one has west as the off position. In the case of your observer there is only one “facing down” texture, either an east-west one or a north-south one.
