low oil pressure

I started to see the low oil pressure a few days ago. After seeing a leak from my oil pan, so I pulled it and replaced to gasket and clean the pan and what I could get to. Put in new oil and ran the truck and all looked good. Or so thats what I thought. After a short drive i lost oil pressure again but no leak. so I got a new oil pump, oil pressure switch, oil and oil fitter. So i was up late last night and pulled and replaced the oil pump but I do not know where the oil pressure switch is located. Can anyone help me find the oil pressure switch?

No the oil pressure switch is located by the distributor on the left side towards the drivers side
