1978 Honda CB550K · Switches & Sensors Buying guide

Identify the switch by its job and mounting location

A front hydraulic switch, rear brake switch and engine oil-pressure switch are separate components. Compare the removed part’s mounting and connections; the shared category does not make them substitutes for one another.

Parts to consider

Honda CB Hydraulic Stop Light Switch ~ Replaces 35350-300-006 Hydraulic brake-light switchA front brake-light switch with a stated 10mm x M1.25 thread. Compare the installed fitting and connections before choosing it for the present brake system.View part Honda CB Rear Brake Light Switch Rear brake-light switchA separate stop-light switch listed for the rear brake application. Compare the fitted switch body, support and connections rather than treating it as the front hydraulic option.View part Honda CB Oil Pressure Switch ~ Replaces 37240-P13-013 Oil-pressure warning switchAn engine oil-pressure switch referencing 37240-P13-013. Identify the installed switch and warning-circuit connection; the listing does not establish the cause of an oil warning.View part

Distinguish the two brake-switch arrangements

The hydraulic front option specifies its thread, while the rear stop-light switch is a different assembly. A separate clutch/brake switch listing describes non-hydraulic applications. Compare the actual switch location and connections before ordering; the word “brake” alone does not establish interchangeability.

Keep the warning circuit and cosmetic cover separate

The oil-pressure switch serves the engine warning circuit. The indicator-cover product in this section instead describes front and rear covers with fastening screws. Choose it for a cover repair, not as a replacement sensor, and do not treat a new switch as proof that an underlying warning is resolved.

Common buying questions

Can the non-hydraulic switch replace the hydraulic option?

The two listings describe different applications. The hydraulic switch specifies a 10mm x M1.25 thread, while the clutch/brake switch is identified for non-hydraulic use. Match the installed arrangement rather than assuming they substitute.

Does the oil-pressure switch diagnose an oil warning?

The listing identifies a replacement switch and its reference number. It does not establish why a warning appears. Confirm the required component and investigate the warning separately before assuming that replacement will resolve it.

Is the indicator cover an electrical sensor?

The indicator-cover listing describes front and rear covers with fastening screws. It is a housing repair purchase, rather than an oil-pressure sensor or brake switch; choose according to the component that needs replacement.
