Pressure Switches – Monitor hydraulic, pilot, brake, transmission, engine oil, or air conditioning refrigerant pressure. These switches trigger warning lights, safety cutoffs, or system engagements at preset pressure thresholds. Key applications include:
Hydraulic system pressure warning
Pilot pressure confirmation for boom/arm/bucket control
Brake accumulator pressure monitoring
Transmission clutch pressure verification
Engine low oil pressure protection
A/C compressor clutch cycling
Available in normally open (NO) or normally closed (NC) configurations with thread sizes matching original Case specifications (NPT, BSP, metric).
Temperature Switches/Sensors – Measure coolant, hydraulic oil, transmission fluid, engine oil, or intake air temperature. These sensors send real-time signals to the dashboard gauge or ECU for overheating prevention and optimized performance. Common types include:
Coolant temperature sender (for gauge or ECU)
Hydraulic oil temperature sensor
Transmission temperature switch
Engine oil temperature sensor
Intake air temperature (IAT) sensor
Limit Switches – Detect mechanical position or end-of-travel on moving components such as stabilizers, boom height, attachment coupler, parking brake, and pedal position. These switches improve safety and machine logic by signaling the control module. Typical applications include:
Stabilizer down/up position detection
Boom height limit for overhead clearance
Attachment quick-coupler lock confirmation
Parking brake engagement indicator
Auto-deceleration pedal position
