1983 Honda CB650SC Nighthawk · Switches & Sensors Buying guide

Identify the switch by its operating location

The rear brake-light switch, clutch starting-interlock switch and oil-pressure switch serve separate circuits. Use the wiring diagram and appropriate service checks to identify which circuit needs attention before selecting the replacement.

Pedal and lever switches serve different controls

The rear stop-light switch responds to the rear brake pedal. Switch 35330-MB0-003 instead provides the starting-interlock signal at the clutch lever. Compare each switch’s connectors and mounting details with the fitted control rather than interchanging components because their leads look similar.

Treat an oil warning seriously

The featured oil-pressure switch is listed as a genuine Honda part for the later CB650SC. A warning may require pressure diagnosis, not merely a switch replacement. Use the correct service procedure or qualified help before returning the motorcycle to use. If the oil-pressure warning stays on with the engine running, stop the engine and have actual oil pressure checked before riding.

Switches & Sensors questions

What should I check before ordering the rear brake switch?

Compare the pedal-operated switch, mounting arrangement and connector with the fitted part. The product lists the 1983–85 CB650SC; changed controls or wiring still need an exact match.

How do I identify the clutch lever switch?

The selected starting-interlock switch replaces reference 35330-MB0-003. Compare its mounting and electrical connection at the clutch lever, especially if the clutch control assembly has been replaced. Use the correct starting-circuit checks rather than treating it as a brake-light switch.

Is the oil-pressure switch genuine Honda?

The selected product is described as genuine Honda and lists the later CB650SC application. Compare its references and connection with the fitted part before ordering.
