12P Marine Switch Panel with 3.1A Dual USB and Digital Voltmeter for Boat and RV 12V 24V Control

AS173 12P Aluminum Switch Panel with 12V Power Socket, 3.1A Dual USB and Voltmeter

The AS173 fits twelve switch positions, a 12V power socket, a 3.1A dual USB charging socket and a digital voltmeter onto one aluminium face plate. It turns a plain console into a complete 12V and 24V control point: accessories are switched, phones and tablets are charged, plug-in gear still has somewhere to go, and battery voltage stays visible while the vehicle or boat is running.

AS173 At a Glance

• Model: AS173, 12P (12 gang) switch panel on an aluminium face plate.
• Outlets: one 12V power socket plus a dual USB socket rated 3.1A total.
• Metering: digital voltmeter showing live battery voltage.
• Lighting: blue, red or green LED legends. Voltage: 12V-24V DC.
• Price: negotiable, quoted per order.

What the AS173 Panel Offers

• Twelve switch positions, so pumps, lights, wipers, horns, radios and work lights each get their own circuit.
• 12V power socket for plug-in coolers, spotlights, inflators, vacuum cleaners and other 12V accessories.
• Dual USB socket with 3.1A combined output, enough to charge a phone and a tablet at the same time without slow trickle charging.
• Digital voltmeter that keeps battery condition in view, so a weak battery or a failing alternator shows up before it strands the operator.
• Aluminium face plate that stays flat under vibration and does not chalk, warp or crack like plastic after a few seasons outdoors.
• LED backlight in blue, red or green so switch status stays readable after dark.

Why Buyers Choose This Layout

Charging and switching together. Phones, tablets, GPS units and plug-in accessories are served by the same plate that switches the rest of the circuits, so no separate socket panel is needed on the console.

Real charging speed. The 3.1A dual USB output is split across two ports, which keeps a modern phone charging at a usable rate instead of the slow top-up most budget sockets deliver.

Battery state on display. The voltmeter turns an invisible electrical problem into a number, so a battery heading for failure is replaced at the dock rather than at sea.

Metal where it matters. The aluminium plate holds the switch bodies square and keeps the face flat, so rockers do not bind after seasons of vibration.

Typical Installations

• Marine: helm switch banks on sailboats, motor yachts, ribs, fishing boats and pontoons.
• RV and camper: lighting, water pump, vent fan and accessory circuits on coaches and van conversions.
• Off-road and utility: tractors, UTVs, ATVs, trucks and work trailers.
• Special vehicles: ambulances, emergency response vehicles, food trucks and mobile workshops.

Questions Buyers Ask

Q: How many circuits does AS173 switch?
Twelve, in a 12P layout, with the 12V power socket and USB sockets on their own feeds.

Q: How fast is the USB charging?
The dual USB socket is rated 3.1A in total, shared between the two ports.

Q: What does the voltmeter read?
Live battery voltage on a digital display, so supply condition is visible while running.

Q: Can the LED colour be chosen?
Yes. Blue, red or green backlight is specified per order.

Q: Does it suit a 24V truck or boat?
Yes. The panel covers 12V and 24V DC systems.

Q: How is the price set?
Price is negotiable, because switch mix, LED colour and quantity all change the cost.
