Sierra MP39580 Marine Push-Pull Switch – Sequential Dual-Circuit On/On
The Sierra MP39580 is a heavy-duty marine push-pull switch built for sequential dual-circuit control on boats and watercraft. Solid brass construction and stainless steel springs deliver the corrosion resistance and long-term reliability that marine electrical panels demand. The sequential action is what sets this switch apart: the first pull energizes circuit 1, and the second pull energizes both circuits 1 and 2 simultaneously — making it ideal for applications where you want staged activation, such as running lights followed by spreader lights, or a blower followed by an engine circuit.
The 3/8" diameter mounting stem fits panels up to 1" thick, compatible with most standard marine dash panels. Rated at 15A @ 12V DC and 25A @ 24V DC.

Parts Desk Insights
The MP39580 is the right choice when you need two circuits to come on in stages from a single switch — circuit 1 first, then both circuits together on the second pull. This is common for lighting setups where you want running lights before activating spreader or cockpit lights. If you only need a simple single-circuit On/Off, the Sierra MP39530 2-Position Off-On Switch is the simpler fit. For a 3-position On/Off/On configuration controlling a single circuit from two locations, the Sierra MP39400 covers that application. If your setup requires energizing two completely separate circuits simultaneously (not sequentially), the Sierra MP39600 is the better match.
