Applicable Scenarios

Widely used in quarry, aggregate yard, and earthwork construction sites with frequent braking and heavy-load travel. It is a basic switch accessory for ensuring monitorable brake system pressure status and normal low-pressure alarm functions.

Direct brake pressure monitoring function linked to low-pressure alarm
The pressure switch outputs signals when brake circuit pressure is abnormal, triggering instrument display or alarm to help the driver identify brake system pressure issues promptly.

Threaded screw-in installation for easy replacement
Designed to the brake circuit pressure measurement point interface; replacement requires only screwing in and tightening, shortening on-site repair time.

Can be stocked with brake system accessories for the same model
Can be stocked together with booster pumps, brake valves, air reservoirs, and related brake system accessories for the same model, facilitating complete procurement during brake system maintenance.

FAQ 

Q：When does a brake pressure switch need replacement?
A: Inspect or replace when brake low-pressure alarm is abnormal (fails to alarm when it should or false alarms), no pressure signal output, switch interface oil seepage, housing damage, or terminal corrosion occurs.

Q：Is brake alarm abnormality always caused by the pressure switch?
A: Not necessarily. Check whether actual brake circuit pressure is normal, accumulator precharge meets specification, and alarm circuit and instrument are normal first. Inspect the pressure switch for failure after confirming system pressure and circuit are normal.

Q：What to note during brake pressure switch installation?
A: Confirm the switch thread specification matches the measurement point interface. Clean around the measurement point before installation to prevent contaminants from entering the brake circuit. Tighten to specified torque to avoid thread damage from over-tightening or oil leakage from under-tightening. Align connectors during wiring.
