Precision Sensors puts on the market the P18M, a polyamide pressure switch that offers greater sensitivity in areas of lower pressure, which is where the engine purge air and fuel pressure applications are usually located.

The switches designed with polyimide have a longer life cycle, exceptional temperature performance and also great media compatibility. In order to ensure stable benchmarks during the life of the unit, even during severe shocks and vibrations, a Belleville washer is used.

As for the housings, these are available in aluminum and stainless steel, two materials that are used depending on the weight and installation requirements. Finally, this switch works perfectly in a wide temperature range, this being from -18ºC to + 120ºC. You can see more information in the following link.
