Aluminum Marine Switch Panel with Overload Protector and Ammeter Voltmeter for Boat and RV 12V 24V

AS21 10P Aluminum Switch Panel with Overload Protector, Ammeter, Voltmeter and Power Socket

The AS21 puts ten switch positions, an overload protector, a current and voltage meter and a 12V power socket onto a single aluminium face plate. Yards and van builders use it as the main distribution point on a dashboard: one cut-out, one wiring loom, and every accessory circuit on the helm is switched, protected and readable at a glance. It works equally well on 12V and 24V systems.

AS21 At a Glance

• Model: AS21, 10P (10 gang) aluminium rocker switch panel.
• Protection: built-in overload protector on the panel feed.
• Metering: ammeter for live current draw plus voltmeter for battery voltage.
• Outlets: one 12V power socket, ten switched circuits, blue/red/green LED legends.
• System voltage: 12V and 24V DC. Price: negotiable, quoted per order.

What the AS21 Panel Offers

• Ten switch positions in a 10P layout, each labelled, so pumps, lights, wipers, horns and radios are identified without tracing wires.
• Overload protector built into the face plate, tripping before a fault can damage the loom, the alternator or the battery.
• Combined ammeter and voltmeter showing live current draw and battery voltage, so a failing battery or an overloaded circuit is spotted early.
• 12V power socket for coolers, spotlights, pumps, tyre inflators and other plug-in accessories.
• Aluminium face plate that stays rigid under vibration and resists salt spray, UV and heat far better than plastic plates.
• Blue, red or green LED backlight so switch status is readable on night passages and in unlit cabins.

AS21 Technical Data

Why Buyers Choose This Layout

One plate replaces a rack of parts. Switching, protection, metering and a power outlet share the same plate, which cuts wiring hours at the yard and removes four extra cut-outs from a console.

Protection before damage. The overload protector trips on a fault instead of letting a short circuit cook the harness, and it can be reset on the water without a spare fuse.

Numbers instead of guesswork. Current draw and battery voltage are visible while running, so an operator can see a failing battery or a circuit drawing too much before it fails.

Rigid under load. The aluminium plate holds switch bodies square, so rockers do not bind or rattle after seasons of vibration.

Legible at night. Backlit legends stay readable when cabin lighting is off.

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, fire units, food trucks and mobile workshops.

Questions Buyers Ask

• Q: How many circuits can the panel carry?
  Ten, in a 10P layout. The overload protector covers the incoming feed for the whole bank.
• Q: What exactly do the meters show?
  One shows live current draw, the other shows battery voltage, so both load and supply state are 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 working range covers both 12V and 24V systems.
• Q: How is the panel priced?
  Price is negotiable and quoted per order, because switch mix, LED colour and quantity change the cost.
• Q: Is every unit tested?
  Yes. Each panel is checked for switching, overload trip, meter accuracy and socket contact before packing.
