What does the car PTC switch mean?

[RyleeLee]

PTC switch in a car refers to the car heater switch. 1. Introduction: Temperature PTC can be used as a ceramic heating element for car startup in low-temperature conditions. We can design it into different structural forms such as tubular and flat-plate types, which results in the full utilization of the heat efficiency generated by PTC. 2. Function: It is generally directly fixed on the inner wall of the vaporization chamber, where it directly heats the gasoline inside the vaporization chamber, rapidly increasing its temperature. This improves the fuel combustion and vaporization effect, which not only helps the car to start normally in low-temperature environments but also reduces pollution caused by car exhaust emissions and decreases fuel consumption.
