Thwaites Pressure Switch - OEM Number: T50532

The Thwaites Pressure Switch (OEM T50532) is a genuine replacement electrical control component designed for use on selected Thwaites site dumpers. The pressure switch monitors hydraulic or lubrication system pressure and automatically opens or closes an electrical circuit when a predetermined pressure threshold is reached, helping to protect the machine and ensure safe, reliable operation.

Manufactured to OEM specifications from high-quality, durable materials, the pressure switch is engineered to withstand vibration, pressure fluctuations, moisture, and the demanding conditions encountered on construction and civil engineering sites. Precision-manufactured for an accurate fit and dependable performance, it is designed as a direct replacement component to restore the correct operation of the machine's monitoring system.

FUNCTION AND OPERATION

• Monitors system pressure during machine operation
• Activates or deactivates electrical circuits at preset pressure levels
• Supports safe and reliable machine operation
• Helps protect critical hydraulic or engine systems
• Withstands vibration and harsh operating conditions
• Designed for heavy-duty construction applications

TECHNICAL DETAILS

• OEM Part Number: T50532
• Type: Pressure switch
• Function: Pressure monitoring and electrical switching
• Application: Selected Thwaites site dumpers
• Material: Durable metal and composite construction
• Design: OEM direct replacement component

TYPICAL APPLICATIONS

Suitable for selected Thwaites equipment, including:

• Front tip site dumpers
• Swivel skip dumpers
• Hi-tip dumpers
• Other Thwaites machines fitted with the compatible pressure monitoring system

Always verify compatibility using the machine model, serial number, and OEM part number before ordering, as pressure switches can vary in pressure rating, thread size, electrical connector type, and switching characteristics between machine models and production revisions.

IMPORTANT INFORMATION

Always confirm the correct OEM part number, machine model, serial number, and system specification before ordering, as pressure switches are manufactured to precise electrical and pressure requirements. Installing the correct component is essential to ensure accurate pressure monitoring, reliable warning system operation, and safe machine performance.

Common signs that a pressure switch requires replacement include incorrect warning light operation, intermittent electrical faults, pressure-related fault codes, oil or hydraulic fluid leaks around the switch, damaged electrical terminals, or complete switch failure. When replacing the pressure switch, it is recommended to inspect the wiring harness, electrical connectors, sealing washer, threaded port, and associated monitoring components for signs of wear or damage. Replacing any worn associated components at the same time will help maximise the reliability and service life of the complete pressure monitoring system.
