1973 Honda CB350G · Brake-Light Switches Buying guide

Distinguish the two brake-light switch circuits

Front brake hydraulics, the rear switch and the connecting wiring need separate checks. Match the replacement to its actual location and retain the correct wiring arrangement during any brake or control changes.

Choose the switch for the correct brake

The hydraulic switch is the front-brake choice and has an M10 × 1.25 thread. The rear stop switch is a separate application. Changed master cylinders and brake plumbing can alter what is required, so inspect the actual setup before buying.

Do not overlook the short wiring section

The front stop-switch sub-harness is separately available when its leads or connectors need renewal. Check the adjoining harness and switch terminals as part of diagnosis. Replacing a switch alone will not repair a damaged connection elsewhere in the circuit.

Buying questions

Will the front switch suit a replacement master cylinder?

Identify where the replacement brake system operates its stop-light switch. The offered hydraulic switch uses M10 × 1.25 threads; confirm the port and wiring arrangement rather than assuming every master cylinder uses this switch.

What thread does the front hydraulic switch use?

The offered switch is M10 × 1.25. Compare that thread with the fitted port before ordering, particularly after a master-cylinder or brake-line conversion.

Does the sub-harness include a brake-light switch?

It is the separate wiring section for the front stop switch. Choose the switch as its own item when diagnosis shows both the switch and wiring need replacement.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
