【Superior material】The oil pressure switch is made of high quality aluminium with strong diaphragm and structurally stable spring, lightweight, anti-rust, colorfast, high temperature resistance. Manufactured 1:1 according to the original parts data. Closer matching with the corresponding fuel system model, making people safer.
【Install Easily】You can replace parts by yourself and solve your vehicle problems. The oil pressure switch is installed in the main oil duct of the engine, near the oil pressure sending unit in the oil pan. Find the old oil pressure sensor, and use raw material tape to wrap the thread before screwing it on, so as to save you a lot of money and time.
【Working principle】It is installed on the main oil duct of the engine. When the engine is running,the pressure measuring device detects the pressure of the oil, converts the pressure signal into an electrical signal and sends it to the signal processing circuit. After voltage and current amplification, the amplified pressure signal is connected to the oil pressure indicator through a signal wire, changing the ratio of the current passing through the two coils inside the oil pressure indicator.
