Paul,  I'm not sure it would make any difference in a no oil pressure
scenario. If  you loose oil pressure all at once, the difference between 
when
the light  comes on from say 15 PSI or 7 PSI is in milliseconds with the
engine  operating, faster than you can react. If you are looking for
something  fairly accurate for normal oil pressure ranges a oil pressure
guage is the  way to go.Mark Durham

There are lots of different pressure switches available. I always installed 
 a higher (~15 psi) on the race cars. Longacre or other racing suppliers 
have  them. I look at them as true "low-oil-pressure" indicators, rather than 
the  "engine-destruct" indicators at around 3-4 PSI. I have seen it (the 
15PSI  one) come on in certain tight corners. If nothing else, it will  
"Make-You-Look" at the gage. I don't know of a stock application that was this  
high, though. I think some MOPAR applications were higher than our stock 
Corvair  ones.
