Cole Hersee 4 Position Brass Ignition Switch

The Cole Hersee 4 Position Brass Ignition Switch (model M-712-BP) is a marine-grade electrical component built for reliability in harsh saltwater and freshwater environments. This brass ignition switch combines corrosion-resistant construction with a proven four-position design: Off, Ignition, Ignition/Start (with spring return to Ignition), and a key-removable-at-off safety feature that prevents accidental starting and protects against theft.

Brass construction provides superior resistance to oxidation and galvanic corrosion compared to plastic alternatives—a critical advantage for vessels operating in salt environments where electrical contacts deteriorate rapidly. The spring-return-to-ignition mechanism ensures the engine automatically returns to a safe idle state if the key is released from the start position, preventing starter overrun. The key-removable function at the Off position meets standard marine safety practice by allowing operators to secure their vessel without worry of unauthorized ignition. At 0.4 lbs and compact 3" × 2" × 7" dimensions, this switch integrates easily into existing marine electrical systems without taking up valuable console or panel space.

This switch is designed for boat owners, fishing guides, and commercial marine operators who depend on dependable ignition hardware. Weekend fishermen upgrading aging plastic switches, offshore anglers replacing corroded electrical components, and recreational boaters maintaining original equipment specifications all benefit from Cole Hersee's engineering. The M-712-BP is a direct replacement for vessels originally equipped with this standard, making it ideal for restoration and maintenance projects across freshwater and saltwater fleets.

Cole Hersee has manufactured marine electrical products for decades, and brass ignition switches remain an industry standard where durability and corrosion resistance matter. Whether you're rebuilding a classic center console, maintaining a commercial fishing vessel, or upgrading from a failing plastic switch, this four-position brass switch delivers the electrical integrity and environmental resistance that saltwater operation demands.
