So I went and upgraded my super charger while at the tuning shop making the first data pass we ran into a problem the brand new double pump fuel pumps that i installed couldn’t keep the fuel that the engine needed so I had to install a 3rd fuel pump I needed a relay and a pressure/vacuum switch to turn on the 3rd fuel pump when needed in comes the Hobbs switch I bought one local from an automotive store and it failed miserably low class low budget switch I checked out Amazon and bought this Hobbs switch installed it and works flawlessly yes it was more money but the quality of this switch is the reason I bought it so take it from me not all components are the same regardless of the packaging it comes in with big fancy words . Thanks Amazon you as always you come through with what I need for a good price and super fast shipping I see no where else to shop than Amazon

I ordered one and the contacts were weak and loose. I ordered another one and it was the same. The contacts are barely attached and do not make good electrical contact. This is a cheap piece of junk that will not work for you. Go spend $50 on a real one.

This part was purchased to turn on a fuel pump at 4 psi, and it may have worked one time, before it broke. Luckily we caught it, and it didn't damage our engine. Do NOT buy.

Magnetic, painted. Get what you pay for I suppose. Not suitable for marine applications.
