How to Choose a Modular Switch Brand

“Modular” is a fitment system, not a quality grade

This is the single most common misunderstanding, and it costs people money. Modular does not mean better. It means the switches, sockets and regulators are separate units that clip into a grid plate, so you can mix them and change them later. A modular switch is not automatically safer or longer-lived than a piano-type one — it is a different way of assembling the board.

Module The unit of width. A 1M switch takes one slot, a 2M socket takes two. Plates come in 1M, 2M, 3M, 4M, 6M, 8M, 12M and 18M sizes.

Grid plate The metal frame behind the visible plate. The modules clip into this, not into the wall box.

What modular actually buys you Change one switch without touching the rest of the board. Change the finish without rewiring. Add a socket later into a spare slot.

What it does not buy you Quality. That comes from the contact material, the standard the product is made to, and whether anyone tested it — which is what the rest of this guide is about.

Start with the licence number, not the brochure

Every other question is secondary to this one. Switches and sockets fall under mandatory BIS certification in India, and a certification is a licence granted to a specific factory to make a specific product to a specific Indian Standard. That licence has a number, and the number is checkable by anyone in about a minute.

Ask for the CM/L number Then look it up on the BIS public licence database and confirm it resolves to that product, that standard and that manufacturer.

An ISI logo with no number Not a certification. It is a printed shape.

“ISI type” or “ISI standard” Deliberate wording that avoids making a certification claim.

Expect IS 3854 for switches, IS/IEC 60898-1 for MCBs and IS 16102 for LED lamps. Number on the product Not only on the carton, which is easy to copy.

What are the top modular switch brands in India?

The modular switch brands most buyers in India compare are the national names Anchor by Panasonic, Havells, Legrand, GM Modular, Goldmedal, Polycab and Crabtree, plus manufacturer ranges sold through electrical dealers, such as our own KEMPS and VIZA modular ranges, made in Mumbai alongside our conventional VIYONA series.

That short list is drawn from three kinds of seller, and the questions here work on all three.

National brands Wide reach and heavy advertising, which says nothing about the contact inside the switch.

Manufacturer ranges Companies that make what they sell, usually through dealers. We are one: we make KEMPS and VIZA modular ranges and the VIYONA series at our works in Marol, Andheri East, Mumbai.

Relabelled stock Made by someone else, sometimes imported, sold under a trader’s label. Ask who the maker is.

We are not going to rank them: a manufacturer scoring its competitors is not information. What we can do is set out what actually separates one modular range from another — checks that work on any brand, including ours.

Apply every question below to us too If a criterion only works when pointed at someone else, it is marketing, not a criterion.

For who owns each of these names and what each one makes, see our top 10 switch brands in India, and for the ownership question on its own, which electrical brands are Indian-owned.

What is actually inside the switch

The visible plate is the part you choose in the shop and the part that matters least. What decides whether a switch is still working in ten years is the contact — the piece of metal that carries current every time it is pressed.

Silver or silver-alloy contacts What a mains switch should use. Silver resists the pitting that arcing causes.

Contact rating A 10 AX switch is rated for capacitive loads such as LED drivers; a plain 10 A rating is not the same test.

Thin brass at the socket contact This is where cheap accessories fail. Under a sustained 16 A load an under-specified contact heats, and heat at a live connection is how fires start.

Weight in the hand Crude but useful. Two switches of the same size and very different weights do not contain the same amount of metal.

Will the range still exist in five years?

Nobody can promise that a range will be made forever, so judge it on evidence you can check today: how long it has already been in production, whether its plates will take modules from other systems, and whether your local dealer stocks spares in depth. A range that passes all three is the safer choice for a board you will keep for years.

Ask how long the range has been in production Years behind it suggests years ahead.

Ask what happens when it is discontinued Is the grid plate carried forward? Do modules from the replacement range fit the old plate?

A range launched this season with a new plate geometry Attractive, and the hardest to get spares for later.

A dealer who stocks the range deep Then spares are a walk away rather than an order.

Finish choice is where modular earns its price

This is the legitimate reason to pay more for modular. Because the plate is separate from the mechanism, the same switch can sit behind very different finishes, and you can change the finish later without touching the wiring.

Ask to see the board Finishes photograph badly and vary under shop lighting. Switches sell off a display board because pressing the rocker tells you more than a catalogue page.

Check the finish is available in every module size you need A range that offers a finish in 2M and 4M but not 6M forces a mismatch on the bigger boards.

Ask whether white plates yellow Pale plastics in sunlight can discolour over the years.

Count your modules before you choose anything

Most board problems are arithmetic, not brand. Work out the module count per location first, then choose, because it changes which plate sizes you need and sometimes which range can supply them.

Add up the modules Each switch, socket, regulator and indicator takes 1M or 2M. Total them per board.

Leave a spare slot One spare module per board is the cheapest future-proofing there is. Adding a socket later into a spare slot is trivial; adding one to a full plate is a rewire.

Check the wall box The metal box already in the wall constrains the plate size. A 6M plate does not fit a 4M box without cutting. Our guide to modular plate sizes gives device widths and a worked bedroom count.

Buying plates before counting The commonest reason a board comes back to the counter.

The plate size calculator does the sum for you.

How to choose a modular switch brand on module sizing, plate fit and warranty

Every modular brand counts in modules; what can differ between systems is how a module clips into the frame. So the useful question is not “which brand are these modules?” but “what will this plate accept?”

1M one switch or bell push. 2M most sockets and regulators.

Plates built for major systems Our KEMPS and VIZA plates are made to fit all major modular switch systems.

Seat one module at the counter With any unfamiliar plate, clip one module into the frame before buying the rest.

Warranty also varies, and is rarely on the shelf label.

5-year plate warranty What our plates carry. Warranty in writing Ask what is covered, and for how long. A warranty nobody will name If the counter cannot tell you the period, assume there is none.

Where the product is actually made

A brand name on a box is not a factory. Some ranges sold in India are made by the company whose name is on them; others are manufactured by a third party, sometimes imported and rebadged. Neither is wrong, but it changes who you are dealing with when something goes wrong.

A named works you can visit The strongest answer. We make ours at our own works in Marol, Andheri East, Mumbai — this is what that looks like.

“Marketed by” on the box Means the seller is not the maker. Ask who the maker is.

Full manufacturer address on the packaging Legally required, and its absence tells you something.

Why it matters A certification is tied to a factory; if you cannot identify the factory, you cannot verify the certification.

ISO 9001:2015 A quality-management certificate; it does not replace a CM/L number.

Price: what you are comparing when you compare two switches

Two modular switches with the same rating can differ widely in price, partly finish and partly material you cannot see. Compare the whole board, not the headline switch price.

Our own catalogue shows why. A KEMPS K101 10AX one-way switch is ₹65 and a VIZA V101 10A one-way is ₹56, yet an 8M plate runs from ₹130 to ₹870 depending on the finish.

Compare a whole board Same module count, same finish tier, both quotes including plates.

A price far below everything else Certification, testing and correct contact material all cost money. A price well under the market is telling you which was skipped.

MRP We publish MRP on every product page — see the catalogue.

The questions worth asking any brand, including us

Take these to any counter. A brand that answers all eight without hedging is telling you something.

1 What is the CM/L licence number for this switch, and which IS is it made to?

2 Who manufactures it, and where is the works?

3 What are the contacts made of?

4 How long has this range been in production?

5 If it is discontinued, will modules still fit my plate?

6 Which module sizes is this finish available in?

7 Does my local dealer stock it, or is every spare an order?

8 What does the warranty cover, for how long, and is it written down?

The short version

If you remember four things from this, make it these.

Check the licence number Not the logo, and not the brochure. It takes a minute on the BIS database.

Count modules before you choose a range And leave one spare slot per board.

Ask about spares in five years A modular board is a long-lived install and the plate is the part you are committing to.

Ask what the plate accepts Module clip detail can differ between systems, so choose a plate built to take the major ones — ours are — and seat one module before you buy.

To go deeper, our switch board guide covers plates, sizes and room-by-room counts, and the range guide sets out what sits where across KEMPS, VIZA and VIYONA.
