Do I need to drain oil to replace oil pressure sensor?

I'll be picking up a new oil pressure switch on Monday, and was wondering if I need to drain the oil before I remove the old one? Let me answer my own question - you don't need to.

How does oil pressure sensor work?

Standard oil pressure sensors work by displaying a warning signal when the oil pressure falls outside of the set range. As the force of the oil pressure starts to build on the diaphragm, this force overcomes the switch spring pressure, which then pulls apart the electrical contacts to turn on the warning light.
