Differential Lock Pressure Switch 81.25503.0244 Shacman

Product Introduction

This precision pressure switch is a key component of the differential lock system, designed to detect hydraulic pressure and send a signal to the vehicle’s dashboard (indicating lock status) when the differential lock is activated.

Structure & Material

• Material:

• Housing: Corrosion-resistant brass for durability and pressure resistance.

• Internal components: High-strength steel contacts and a rubber seal for leak-proof performance.

• Connector: Heat-resistant plastic for secure electrical connection.

  • Design: A threaded brass body with a pressure-sensitive plunger, paired with a weather-sealed electrical connector (to prevent moisture ingress).

Performance

• Pressure Detection: Triggers an electrical signal when hydraulic pressure (typically 8–12 MPa) reaches the threshold for differential lock engagement.

• Status Feedback: Sends a signal to the dashboard indicator light, letting the driver confirm the lock is active.

• Weather Resistance: Sealed design protects internal components from water, dust, and road debris.

Durability

• Brass construction resists corrosion from hydraulic fluids and environmental exposure.

• Sealed electrical connector ensures reliable signal transmission over long service life.

Core Function

1. Pressure Monitoring: Detects hydraulic pressure to confirm differential lock activation.

2. Driver Feedback: Sends a signal to the dashboard indicator light for lock status.

3. System Safety: Ensures the differential lock is fully engaged before the driver operates the vehicle in low-traction conditions.
