1979 Honda CB400TII Hawk II · Switches & Sensors Buying guide

Identify the switch at the failed circuit

The front stop switch, rear stop switch and oil-pressure switch have distinct mounting and electrical connections. Start with the component location, then compare the actual fitted control and wiring.

Choose the front switch for the fitted control

The 1979 Type II front master cylinder has its own Honda addendum and stop-switch reference. Use the current control to check the switch, especially if the brake assembly has been replaced. Compare the plunger and electrical terminals before assuming a switch for another Hawk year will suit.

Check the fault before replacing the warning switch

A warning lamp that behaves incorrectly can have a wiring or connection fault as well as a failed switch. Inspect the terminal and follow the Honda diagnostic procedure before ordering. An oil-pressure warning that remains on needs its cause checked before further running, rather than being treated as a switch diagnosis.

Common buying questions

Does the 1979 front switch suit any Hawk master cylinder?

No blanket interchange is established. This switch replaces reference 35340-422-013 for the 1979 CB400TII application. If the master cylinder has been changed, identify its switch mounting and terminal arrangement before choosing a replacement.

What should I check if the rear brake light comes on too late?

Inspect the pedal linkage and switch adjustment before ordering a new switch. Honda provides a rear stoplight adjustment procedure. A damaged switch, broken linkage or incorrect adjustment should be distinguished before buying the replacement.

Should I buy an oil-pressure switch whenever the lamp stays on?

Have the cause checked first. A persistent warning can represent a pressure problem or an electrical fault. Compare the switch connection and use the correct diagnostic procedure; replacing the switch alone is not evidence that the warning is resolved.
