Blue Sea Marine Push-Button Switches: 10A, 15A & Momentary
Blue Sea marine push-button switches vary by actuation, amperage and wire connections. A maintained switch stays in its chosen state; a momentary button only closes its circuit while pressed. Compare the exact part numbers before replacing a panel switch.
Match the control action first
The 4160-BSS, 4162-BSS and 4180-BSS are listed for maintained ON/OFF control. The 4161-BSS, 4163-BSS and 4181-BSS are momentary models. Check the existing switch's function, mounting opening, electrical circuit and indicator wiring before replacing it.
Electrical fitment: The listed 10A products use quick-connect terminals, while the 15A models use wire pigtails. Rated current alone does not establish suitable wire size, voltage, illumination requirements or panel cutout. Follow the exact manufacturer drawing and protect circuits correctly.

10A versus 15A switch families
The four 4160-series switches share a 10A catalog rating and quick-connect terminals but are not necessarily interchangeable: compare exact indicator functions and the wiring diagram in addition to maintained or momentary operation. The 4180-BSS and 4181-BSS are 15A pigtail models with different control action.

Before installing
Disconnect the power source, mark the existing wires and verify panel clearance. Use the appropriate overcurrent protection and manufacturer's wiring diagram. Check switch action and any indicator illumination before returning the circuit to service.
For connected distribution hardware see our marine and RV battery protection guide. For another switch family compare the Sea-Dog push-pull and horn controls.
Common questions
Can I replace a maintained switch with momentary?
Not as a direct substitute. The momentary type activates only while pressed.
Are all 10A Blue Sea push buttons interchangeable?
No. Compare the exact model's circuit action, illumination, terminals and mounting drawing.
