I'm an engineering student, and I was given a task to make this circuit a pcb in Autodesk Eagle. I'm almost done,except I have no idea what J1 J3 J4 and S1 parts are on the circuit, I tried looking through documents on electronic signs and symbols, but as you might have guessed, I found nothing because I'm here. I'd be forever grateful if someone could tell me atleast the name of whatever part that is so I have a word to search in the Eagle library.
Thank you in advance!

Welcome to AAC!

J usually designates an off-board connection. The connector type varies. 0.025" square male/female headers are common, but they could also be some polarized connectors with locking features.

S1 makes me think it's an off-board connection to a switch.
