Vacuum Pressure Switch

Anyone got any clues where I can get a vacuum pressure switch which operates a warning light on low vacuum. Cannot find any in Adelaide Thanks

Use Google, a few should come up, you can see if any of them are suitable. Maybe not Adelaide though

Vacuum or pressure? Each one is a different side of zero?

Try Baccara Australia, thats where I bought the last one for my Dodge, or RS components.

I seem to remember taking some sort of what i thought was a vacuum switch off of the manifold on my forklift when i removed the LPG setup and converted it back to petrol.
Would an LPG setup use a vacuum switch anywhere? Maybe to activate a solenoid to switch the gas on when there is vacuum? Don't know how that would go as far as coming on/off at the right time for a warning light though, and might be normally open when i imagine you would want normally closed. Might be worth asking an automotive LPG or forklift specialist?

Otherwise you might have to raid a parts truck somewhere for a secondhand switch.

Had a quick Google, appears a lot of the ones in there are showing as out of stock.
Another option would be one of these

You can set the alarm point.

Get onto Google....Dial up "Power brake booster valve".........
I just got one for a C63 Chev..Ex USA Cost about $60 landed at my front door
Same valve for the Chev was listed for '80 to '88 Ford F700
Hope this gets you what you want !!!!!!!!!!!

I would imagine that just about every car on the road would have one. Have you tried somewhere like Ashdown or JAS?

"vacuum tank switch" typed into ebay brings one up.
