1978 Honda CB750A Oil, Brake-Light & Button Parts

These parts serve three functions on the CB750A: the oil-pressure switch, rear brake-light switch and a small button with its spring. Identify the component in front of you. A shared switch category does not turn a button repair into a complete control assembly.

1978 Honda CB750A · Switches & Sensors Buying guide

Name the function before choosing the replacement

The oil-pressure switch has a stated replacement reference, the rear switch is identified by its brake-light function, and the button includes a spring. Keep those component identities with the actual fitted controls.

Keep rear brake-light parts separate from other controls

The selected rear switch is named for the rear brake-light function. It should be compared with that installed component, rather than chosen as an oil-pressure switch or a complete handlebar control. Read its described contents before adding any separate actuating or mounting pieces required by the existing arrangement.

Check the small button against its existing housing

The button description lists a spring and says it can serve as a horn or starter button. It does not describe a complete housing, wiring loom or control assembly as supplied. Compare the button and its fitted position, keeping the motorcycle’s existing control arrangement in view before choosing the replacement.

Common questions

Is the button product a complete handlebar switch?

The listing describes a button with a spring, usable as a horn or starter button. It does not describe a complete handlebar switch assembly. Compare the small component in the existing housing rather than expecting an entire replacement control.

What reference is stated for the oil-pressure switch?

The oil-pressure switch description states replacement reference 37240-P13-013 and includes the CB750A application. Compare that identity and the fitted connection before ordering. No oil-pressure operating threshold is given here, so do not choose it by an assumed pressure setting.

Does the rear switch description list a spring package?

The selected rear brake-light switch description identifies the switch but does not list a separate spring package as supplied. Inspect the existing switch arrangement and confirm any additional pieces needed, rather than adding unlisted contents to the switch purchase.
