well pump wiring

I have a Franklin 240v pump and pressure tank.Standard stuff. I was looking inside the control box and along with the wiring buss I saw 2 large round canisters ,1 a little bigger than the other. They looked like a coil in a car.
Are these capacitors used to start the pump??

One may be a start capacitor and one may be a run capacitor. They are definitely used to start/run the pump. Some of those control boxes contain a start relay also.
