Keep an eye on what matters most under the hood with the Standard Ignition Engine Oil Pressure Switch, PS-111. This oil pressure switch drops in as a direct-fit replacement for the 1966-1967 Chrysler Imperial, sensing engine oil pressure and signaling the dashboard warning light or gauge so you know when pressure falls outside the normal range.

  • Monitors oil pressure: reads engine oil pressure and switches the circuit to drive the instrument-panel warning lamp or gauge.
  • Direct-fit replacement: serves as a direct-fit replacement for the listed application.
  • Threaded installation: threads into the engine's oil-pressure port for a secure connection.

If a faulty original switch is the cause of an oil light that stays on, flickers, or fails to illuminate, the PS-111 replaces it. Because those symptoms can also come from other causes, diagnose the underlying issue before replacing the switch.
