Seachoice Heavy-Duty 3-Position Push-Pull Switch – Off/On#1/On#2
A heavy-duty push-pull switch that controls two completely independent circuits from a single knob. Push fully in for Off; pull halfway out to activate Circuit 1 only; pull fully out to deactivate Circuit 1 and activate Circuit 2 only. Each pull position switches to a different, independent circuit — making this the right switch when you need to select between two separate loads, not stack them.
The brass hex backup nut and brass washer provide a secure, corrosion-resistant panel mount, and the chrome-plated plastic knob gives it a clean, finished appearance at the helm.
Key Features
- 3-position action: Off – On#1 only – On#2 only (fully independent circuits)
- Controls two separate circuits — each pull position activates a different circuit exclusively
- Brass hex backup nut and brass washer for secure, corrosion-resistant panel mounting
- Chrome-plated plastic knob
- Mounting stem: 1 ¼ in long × 3/8 in diameter
Compatible Applications
- Navigation lighting — running lights on one pull, anchor light on the other
- Dual-zone cabin or courtesy lighting with independent circuit selection
- Any 12V application requiring a single knob to select between two independent circuits
- Choke and accessory circuit selection on older helm panels

Parts Desk Insights
Best Use Case: This is the correct switch when you need to select between two independent circuits — the classic example is a navigation light panel where one pull position activates running lights and the other activates the anchor light, with neither circuit active at the same time. This is a fundamentally different behaviour from the Off/On#1/On#1+#2 version (50-11911), which stacks both circuits on the second pull. If your application needs both circuits on simultaneously at full pull, choose the 50-11911. If you need to switch between two circuits exclusively, this is the right switch. The Cole Hersee M531BP is a comparable alternative worth considering.
