Oil Pressure Gauge Dropping

I have been having a problem with the Oil Pressure Gauge dropping. The oil level is fine. It seems to do it after the engine has had the chance to warm up. We think it might me the Oil Pressure Sending Switch. Has anyone else had this problem or have any ideas of what might be causing this?
 
That would definetly be your sending unit causing the problem. The switch does not actually read pressure, there is either oil pressure or there isn't. If the guage falls all together, that would be a MAJOR problem, but as long as the guage rises, you can blame the sending unit itself for the low pressure reading.
