You got the .9 bar switch operation reversed. It is normally open and when the pressure reaches .9 bar, it closes completing the circuit. This is a fail safe as having the wire fall off will cause the buzzer to sound. Unlike the low pressure sender where folks do not notice the light does not work before starting the engine.
