Red neon indicator, 1 module, 240 V AC — a modular "power on" lamp that glows to show that a circuit, socket or appliance point is live.
- Red neon indicator lamp for 240 V AC mains.
- One module wide — clips into the base of a modular cover plate.
- Glows while its circuit is live, as a "power on" signal.
- Two screw terminals on the back, for phase and neutral.
- Draws only a tiny current, so it can stay on all the time.
- Does not switch or protect anything — it only shows that power is present.
- Made in India.
A neon indicator is a small lamp behind a red lens that lights up whenever the supply reaches it. On a modular board it tells you at a glance that a circuit is live — for example that the supply to a geyser, AC or pump point is on, or that the board itself has power.
It takes one module and clips into a modular cover plate and base on a concealed or surface box, next to the switches it serves. Connect it across phase and neutral on the load side of a switch to show that the load is on, or directly across the supply to show that power is present.
How to connect it
- On the load side of a switch — it glows only while that switch is on.
- Straight across phase and neutral — it glows whenever the supply is on.
It takes one module on the plate, the same as one switch, so leave space for it when choosing the plate and box size.
Where to use it
- Geyser, AC and water pump points, to show the supply is on.
- Main and sub boards, as a mains-on light.
- Shops, offices and workshops where equipment must not be left on.
- Boards controlling outdoor or terrace lights that cannot be seen from inside.
How to install
- Switch off the supply at the MCB.
- Connect one terminal to the phase — on the load side of the switch if it should show that the switch is on — and the other terminal to the neutral.
- Clip the indicator into the plate base, fit the plate and switch on to check that it glows.
Electrical work should be done by a licensed electrician with the supply switched off.
Frequently asked questions
- What does a neon indicator do?
- It glows red whenever supply reaches it, so you can see at a glance that a circuit, socket or appliance point is live. It does not switch or protect the circuit.
- Is it a Wi-Fi or smart module?
- No. It is a simple mains indicator lamp with no wireless or smart function.
- Does it need a neutral?
- Yes. The lamp is connected across phase and neutral; without the neutral it cannot glow.
- How much electricity does it use?
- Very little — a neon indicator draws only a tiny current, so it can be left on all the time.
- Can I use it instead of a switch with indicator?
- Yes, if you prefer a separate lamp: fit it beside a plain switch and connect it on the load side of that switch. A switch with a built-in indicator does the same job in one module.
- Which plate and box does it need?
- A modular cover plate with base of the matching range, on a concealed or surface box. It takes one module, the same as one switch.
