1981 Honda CB400TB Hawk Switches & Sensors

Brake lighting, oil-pressure warning and the clutch starting interlock perform different jobs on the 1981 Hawk. Choose the switch for the affected circuit, then compare its mounting and connections rather than treating similar small electrical parts as interchangeable.

Choose the rear brake-light switch by position

The featured brake switch is for the rear brake-light circuit. Compare the mounting and pedal-operated connection on the motorcycle before ordering. A switch attached to the clutch lever has a different purpose, even though both items may appear beside other handlebar and electrical parts.

Keep warning and interlock functions separate

The oil-pressure switch uses replacement reference 37240-P13-013. The linked clutch switch corresponds to 35330-413-003 and allows the starting circuit to respond to the clutch lever. Follow the Honda circuit checks when diagnosing either function; a persistent oil-pressure warning needs investigation before riding.

Buying questions

Is the clutch switch another brake-light switch?

No. The linked component is the clutch starting-interlock switch. Its function is in the starting circuit, so select it for that repair rather than for a rear brake lamp that will not operate.

Does the rear brake switch replace the front switch?

Choose it for the rear brake-light application. Compare the fitted switch and its operating connection; a front brake assembly uses its own arrangement and should be identified separately.

Will a new oil switch cure an illuminated warning lamp?

A switch fault is only one possible cause. Check the circuit and actual oil-pressure condition using the service manual before selecting a replacement; do not treat the purchase as confirmation that the engine is safe to run.

Not sure which part you need?
