Parts Desk Insights
Best use case: This is the go-to switch for a dedicated horn button or a secondary manual start trigger on a custom panel. Its no-cover design keeps the profile slim and the install clean — ideal when the switch is recessed or protected by the panel itself. If your installation is exposed to spray or accidental contact, consider pairing it with a protective cover.
