1978 Honda CB750K · Switches & Sensors Buying guide

Identify the switch application before comparing its small parts

The brake/clutch switch description identifies a particular application, while the neutral switch lists a screw but excludes its O-ring. The oil-pressure switch and its lead are separate purchases, so read the contents for each repair.

Parts to consider

Compare the switch application with the existing controls

The brake/clutch product describes use on bikes without a hydraulic front brake-light switch. That application note matters when identifying the part, particularly after control or brake-component changes. Inspect the actual switch arrangement and use the relevant product instructions; do not treat the category as proof that all switch types interchange.

Read seal and wire inclusions one component at a time

The neutral-switch description includes a screw and excludes the O-ring. The oil-pressure wire assembly supplies a lead and rubber cover rather than a switch. List the pieces required for your repair and compare their individual descriptions before deciding whether to order the switch alone or its supporting parts too.

Common questions

Does the Honda neutral switch come with its sealing O-ring?

Its description says the screw is included but the O-ring is not, and the O-ring is sold separately. Check that separate seal when planning a neutral-switch replacement rather than assuming it is in the switch package.

What application note applies to the brake/clutch switch?

The listing describes applications that do not use a hydraulic front brake-light switch. Compare the component and control arrangement on the motorcycle before selecting it; that note is not permission to interchange unrelated brake-switch systems.

Can the oil-pressure wire assembly replace the switch itself?

It is a different product. The lead listing describes a wire and rubber cover, while the switch listing specifies the switch. Identify the worn component and use each description to choose the items needed.
