Claims

[Scope of utility model registration request]

In a vehicle pressure gauge circuit that detects and displays a detected pressure generated by the operation of a pressure generating source driven by an engine, variable resistance pressure sensors 2 and 8 convert the detected pressure into a resistance value, and the pressure sensor A display circuit 1' inputs resistance value signals from terminals 2 and 8 and displays a pressure value corresponding to the resistance value, and a voltage from a terminal 53 whose terminal voltage changes as the engine of the on-vehicle charging device 5 starts. and a switching element 7 whose opening and closing are controlled by a signal, and the switching element 7 controls the display circuit 1 to display a pressure value according to the resistance value signal after the engine starts. A vehicle pressure gauge circuit featuring:
