Topic: Inexpensive replacement oil pressure switch

[toolguy]

Couldn't see spending close to $40 at the dealership so i took a chance and got this one off Ebay for $6.25 with free shipping. .
Turned out to be  identical to the OE Honda M/C ones, and fits fine . .  short enough to clear the engine case easily. .
It's listed as being for 2000 Honda and Acura cars. .  Made by Original Engine  Mgmt   {OEM}  part number 8008
Here is a link to the guys auction

it sure looks right externally... but are you certain that it's activation/sensory range is identical to OEM?  In other words, the "guts" of this could have been spec'd to flip the switch at a different pressure than on our motorcycles (I dunno if that would be lower or higher).  One wouldn't wanna put this in place only to learn that it was set to switch at an oil pressure far to low for out bikes to feed lubricant to the top end, and have something catastrophic happen with no warning shown.  A few psi the wrong way like that could potentially do it.

Should have PSI range on the box i'd imagine.  Think they are a pretty generic part.  Did a search and range said 10+PSI to 145 PSI so it might not trigger quick enough. 

Do you have the part no?  If so enter it into google or post here so we can get the actual number.

I did some searching on the net for that specific mfger's date. .  operating  pressure was 3-7 pounds.
It's installed, works fine, only difference is when i kill the motor with the kill switch. , the pressure light doesn't
come  back on for about 5-10 seconds after motor stops. . don't remember what it did before as i was having
 light issues. .

I think that's quit normal... as long as ignition switch is on though

The stock switch operates at around 5psi so that seems OK. I like to have a pressure gauge, I wouldn't want to be riding along with only 6psi oil pressure thinking all is well because the light is off.
Obviously, if the oil light is ON it means "stop right now!!!".

Our PSI switch works like this: when cold, it opens when rising pressure exceeds 20 PSI. Once it is opened, it has to 'feel' less than 5 PSI before it will close again. Then it goes back through the cycle again, although once the engine (and switch) is hot, the "Off" mode happens closer to 18 PSI while the 5 PSI stays pretty 'true'.

Interesting, I always assumed the oil pressure switch was just a simple switch, didn't realize it had some hysteresis built in.  Makes me want to cut one open and see what makes it tick.
