# How could I simplify the logic of my 3-floor elevator?

I am taking the Control Systems course in high school and the teacher gave as the first exercise to make a 3 floor elevator.
To make the elevator, 3 push buttons must be used, one to go to the second floor, one to go to the second floor and one to go to the third floor, there is also 1 limit switch on each floor and finally 1 lamp on each floor that is activated when it is on that floor. Only relays / contactors can be used to make the logic circuit.
I was able to realize the elevator without many problems, but I would like to know if there is a way to simplify the logic of my circuit, because I use 14 relays and I do not think it is necessary to use so many.
Here is the photo of the circuit:

P1 is the first floor push button, P2 is the second floor push button and P3 is the third floor push button.
FC1 is the first floor limit switch, FC2 is the second floor limit switch and FC3 is the third floor limit switch.

• You've explained everything except the rules of the components you can use. Are they: just relays, switches and lamps? (Please edit this into your question, don't answer in comments.) Commented May 1, 2023 at 20:50
• It would have been much easier to read this as a ladder diagram rather than a wiring diagram :) Commented May 1, 2023 at 21:03
• Have you assembled this circuit, or only ran it in a simulator? Commented May 1, 2023 at 21:09
• @Kubahasn'tforgottenMonica We have not yet learned ladder. Commented May 1, 2023 at 21:13
• I only tested it in the simulator, I didn't put it together in real life. Commented May 1, 2023 at 21:14
