1972 Honda CB500K Warning & Brake-Light Switches

When a warning or brake lamp misbehaves on your 1972 Honda CB500K, identify the switch’s job before replacing it. The oil-pressure switch is an on/off warning component. Front and rear brake-light switches use different operating methods, and small wiring repairs may be separate purchases.

1972 Honda CB500K · Switches & Sensors Buying guide

Match the switch to the warning or brake-light circuit

A warning-light switch, pressure-operated brake switch and mechanically operated stop switch cannot substitute for one another. Compare the relevant location, connector and mounting. The front brake-light sub-harness is wiring only, while the horn button is a small control component.

Diagnose a lamp problem before choosing a sender

The oil-pressure switch supplies an on/off warning signal, not an oil-pressure measurement for an aftermarket gauge. Check the warning circuit and establish the cause of a persistent warning. Replacing the switch cannot repair low oil level, pump problems or other causes of genuinely inadequate pressure.

Check each brake-control circuit independently

The front hydraulic switch and rear mechanical switch are separate ways of triggering the brake light. Confirm which control fails and inspect that circuit’s bulb, wiring and connections. A small front sub-harness may need replacement independently; buying a switch does not include that wiring assembly.

Switches & Sensors FAQs

Is the warning switch suitable for a pressure gauge?

It is specified as an on/off switch for the oil-pressure warning light. A variable pressure gauge needs its own compatible sender. Identify the gauge requirements rather than selecting this warning switch by its threaded appearance.

What distinguishes the two brake-light switches?

The front switch closes through hydraulic pressure and has an M10 x 1.25 thread. The rear switch is mechanically actuated at the rear brake control. Match the operating method and fitted connection before ordering either replacement.

Which reference identifies the separate front stop-switch wiring branch?

Choose by Honda 35345-319-000 and the existing branch connections. The listing supplies one small harness, with the switch and main loom separate. Compare the damaged wiring section before deciding whether this local branch is the assembly needed.
