Parts Desk Insights
Best use case: The M712BP is the preferred ignition switch for helm panel builds and engine repowers where you need a reliable, full-sequence ignition switch with a traditional brass construction. The four-position layout covers the complete start cycle — accessories on, key off, run, and crank — in a single compact unit. It's particularly well-suited for outboard and inboard engine panels, generator controls, and custom console builds. Note that this version does not include an O-ring; if your panel installation requires a sealed gasket for moisture protection, verify compatibility with your panel cutout before installing. For other Cole Hersee switch options for your panel, see the Cole Hersee 558210BP Heavy Duty SPST Toggle Switch and the Cole Hersee M628BP Off/On Push-Pull Switch.
