FAQ

What type of vehicle systems can use this pressure switch?

The PSS7 is suitable for gasoline and diesel engine fuel injection systems, as well as any application requiring precise pressure monitoring within the 5 V control range.

Is the switch compatible with aftermarket engine control units?

Yes, its standard ON‑OFF contacts and screw terminals allow easy integration with most aftermarket ECUs that accept a 5 V control signal.

Can the switch operate in high‑temperature environments?

While the switch is rated for typical engine bay temperatures, it is not designed for extreme heat beyond standard automotive specifications; proper heat shielding is recommended.

What does the IP00 rating indicate?

IP00 means the switch has no special protection against dust or water, so it should be installed in a dry, clean area within the engine compartment.

How do I replace the switch safely?

Disconnect the battery, remove the existing wiring, and install the new switch using the provided crimp connector and screw terminals, ensuring the plunger moves freely without obstruction.
