16A 3 in 1 switch-socket combined with its own surface box (J. box): ON/OFF switch and 6 & 16A universal socket on porcelain bases, ready to fix.
- Complete surface unit: the switch-socket plate and its back box (J. box) together.
- Rated 16A, 240 V AC, as marked on the box.
- 6 & 16A universal socket: six openings take both 6A and 16A round-pin plugs.
- Built-in ON/OFF rocker switch for the socket.
- Switch and socket on heavy porcelain bases, which handle heat well.
- Box marked "Unbreakable box", with two holes in the back for wall screws.
- Plate fixed to the box with four screws.
This is the ready-to-fix version of the 16A 3 in 1 switch-socket combined: the plate with its ON/OFF switch and 6 & 16A universal socket comes with its own surface box (J. box), so you can fix a complete switched power point on the wall without a separate box or board.
Behind the plate, the switch and the socket sit on heavy porcelain (ceramic) bases — generally preferred for high-current points because porcelain withstands heat well. The box is marked 16A-240 V AC and "Unbreakable box".
Already have a box? The plain 3 in 1 plate unit is also available. For a fuse and indicator lamp on the same plate, see the 5 in 1 with J. box.
Where to use it
- Extra power points on walls wired in surface conduit or casing-capping.
- Rented homes, shops and workshops where the wall should not be cut.
- Geyser, room-heater, AC and washing-machine points.
- Temporary site, godown and workshop power points.
How to install
- Switch off the supply at the MCB. A 16A point is typically wired in 2.5 sq mm copper on a 16A MCB.
- Hold the box level on the wall and fix it with screws and wall plugs through the holes in its back.
- Bring the cable into the box, connect phase, neutral (N) and earth (E) as marked, and tighten the terminals firmly.
- Fit the plate on the box with its four screws and switch on.
Electrical work should be done by a licensed electrician with the supply switched off.
Frequently asked questions
- What is a J. box?
- J. box is short for junction box — here, the surface back box that the switch-socket plate screws onto, so the unit fixes straight on the wall.
- What does "3 in 1 S.S. combined" mean?
- S.S. stands for switch-socket. "3 in 1" is the trade name for this unit — an ON/OFF switch and a 6 & 16A universal socket, rated 16A, on porcelain bases behind one plate.
- Will both 6A and 16A plugs fit?
- Yes. The universal socket has two sets of openings — the smaller ones for 6A round-pin plugs and the larger ones for 16A plugs.
- 3 in 1 or 5 in 1 — which should I buy?
- The 5 in 1 adds a fuse and an indicator lamp. Choose it when you want the point to have its own fuse and a light that shows it is on.
- Which wire and MCB does a 16A point need?
- Typically 2.5 sq mm copper wire on a 16A MCB, with a proper earth. Your electrician should size the circuit for the appliance.
- Can I use it outdoors?
- No. It is for indoor walls on AC supply only. For rain-exposed places, use a weatherproof enclosure.
