Sensors, Switches & Control Panel Components

Modern diesel and gas engines rely heavily on a network of sensors and switches to monitor operating conditions and ensure safe, efficient performance. Combined with control panels, these components provide real-time data, automatic shutdowns, and protection against damage — especially in critical applications like generators and marine systems.

At AMS Parts, we supply genuine and OEM sensors, switches, and control panel components, ensuring your engine and generator systems remain responsive, compliant, and protected.

Why These Components Matter

Even minor faults in a sensor or switch can lead to:

  • False alarms or nuisance shutdowns
  • Overheating, oil pressure loss, or unregulated RPMs
  • Generator failure or incorrect voltage output
  • Missed fault codes or inaccurate diagnostics

Regular replacement at service intervals or during overhauls is vital for ensuring reliability and compliance with OEM specifications.

Sensors

  • Oil Pressure Sensors
  • Coolant Temperature Sensors
  • Fuel Pressure Sensors
  • Speed Sensors (Magnetic Pickups)
  • Exhaust Temperature Sensors (EGT)
  • Intake Air Temp & Manifold Pressure Sensors (MAP)
  • Crankshaft and Camshaft Position Sensors

Switches

  • Temperature Switches (ON/OFF)
  • Oil Pressure Switches
  • Fuel Level & Float Switches
  • Emergency Stop Buttons
  • Vibration Sensors / Shutdown Switches
  • Mechanical Pressure Switches

Control Panel Components

  • Generator Control Modules (Deep Sea, ComAp, SmartGen, Woodward)
  • Gauges (RPM, Oil Pressure, Coolant Temp, Voltage)
  • Manual/Auto Selector Switches
  • Engine Start/Stop Relays
  • Control Panel Wiring Harnesses
  • Alarm Panels & Display Units
