Is there any difference between an oil pressure switch, sender, and sensor?

I have an 89 Jeep Cherokee with a busted off oil pressure sensor. AMC 4.0 Liter straight six. Just want to make sure I buy the right parts online. It uses an actual gauge, not an idiot light. What should I buy? Thanks in advance,

It is the sending unit you need and just be sure to tell them it has a gauge if they do not ask you.Most places always ask that anyway.
